Design overview

This library strictly follows Material (Material3) design principles. Considering UI, nepali-date-picker aligns with new androidx.compose.material3.DatePicker.

If you are familiar with the Material3 Date Picker then you will find it very similar, and you can adapt it with little to no time.

This library puts Nepali Calendar in light as OpenSource for developers involved in both Android and/or iOS and/or KMP.

You can use this library independent to any platform or in common Kotlin Multiplatform code.

Types/Features

This library provides variety of features for working with date picker. It is not only limited to date picker but many utilities that serves its purpose with extended support for date and time. Few of them are listed below:

• CustomCalendar - Calendar which represents both English and Nepali dates.
• SimpleDate and SimpleTime - Simple representation of date and time.
• NepaliMonthCalendar - Nepali Month Calendar which consists of the month details.
• NepaliDateLocale - To control language, dateFormat, weekDayName, and monthName.
• NepaliDatePickerLang - Set of supported language (English & Nepali for now).
• NepaliDateConverter - Provides utilities for date conversions (english to nepali and vice versa), get formatted date(6), get time, get date-time in ISO 8601 format, calculate days in between two date, and many more.
• NepaliSelectableDates - To control selectable dates i.e. enable/disable certain dates.
• NepaliDatePickerColors - Takes Material3 ?: Material colors by default. All the colors it uses are taken from your app colors if you've defined Material colors in your project. Also, there's always .copy() to modify the color.

Core UI specific,

• NepaliDatePicker() - Lets you pick a Nepali date via a calendar UI which displays Nepali dates.
• NepaliDatePickerWithEnglishDate() - Nepali date picker lets you pick a Nepali date via a calendar UI which displays both Nepali and English dates.
• NepaliDateRangePicker() - Nepali date picker lets you pick Nepali dates (range) via a calendar UI which displays Nepali dates.
• NepaliDateRangePickerWithEnglishDate() - Nepali date picker lets you pick Nepali dates (range) via a calendar UI which displays both Nepali and English dates.
• rememberNepaliDatePickerState() - To read, write, and manage state of the date picker i.e., NepaliDatePicker()_ and NepaliDatePickerWithEnglishDate()_.
• rememberNepaliDateRangePickerState() - To read, write, and manage state of the date range picker i.e., NepaliDateRangePicker() and NepaliDateRangePickerWithEnglishDate().
• NepaliDatePickerDialog() - A dialog for displaying all four types of date and date range pickers. (or, you can directly use in the layout.)

Using in your projects

The library is published to Maven Central. You can find all artifacts here.

If you encounter version conflicts using this library, you can solve this in two ways:

• Recommended: Update your JetBrains Compose or Android Compose version to 1.7.0 or later to resolve the conflict. For more details on this release, check this release.
• Use an earlier version of the Nepali-Date-Picker library (2.0.0-beta06 or before) if stability is required and your project is using a lower version of JetBrains Compose or Android Compose.

Common Gradle

In multiplatform projects, add a dependency to the commonMain source set dependencies

kotlin {
    sourceSets {
        commonMain {
            dependencies {
                implementation("io.github.shivathapaa:nepali-date-picker:2.2.3")
            }
        }
    }
}

Android

To add the nepali-date-picker library to your Android project, include the following dependency in your module/app-level build.gradle file:

// Add the Compose compiler Gradle plugin to the Gradle version catalog
[versions]
# ...
kotlin = "2.0.20"
nepaliDatePickerAndroid = "2.2.3"

[libraries]
nepali-date-picker-android = { module = "io.github.shivathapaa:nepali-date-picker-android", version.ref = "nepaliDatePickerAndroid" }

[plugins]
# ...
compose-compiler = { id = "org.jetbrains.kotlin.plugin.compose", version.ref = "kotlin" }

// Add the Gradle plugin to the root/project level build.gradle.kts file
plugins {
    // ...
    alias(libs.plugins.compose.compiler) apply false // Kotlin version after 2.0.0
}

// Apply the plugin and dependency to app level build.gradle.kts file
plugins {
    // ...
    alias(libs.plugins.compose.compiler)
}

dependencies {
    // ...
    implementation(libs.nepali.date.picker.android)
}

Android Setup for API Levels Below 26

Note: This library uses kotlinx-datetime, which relies on the java.time API. These APIs are only available natively starting from Android API level 26. For devices running API levels 25 and below, core library desugaring is necessary to backport these APIs and ensure compatibility.

By enabling desugaring, your project will support java.time functionality on older Android versions, ensuring smooth use of this library across all supported API levels. For more details checkout this.

If your project targets Android SDK versions below 26 (Android 8.0), you need to enable core library desugaring to support the java.time APIs used by this library. Directly checkout this or you can follow the steps below:

// Enable Desugaring in your build.gradle (app-level) file
android {
    compileOptions {
        // Enable core library desugaring for java.time (kotlinx-datetime) APIs
        isCoreLibraryDesugaringEnabled = true

        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }
}

// Add the Desugaring Dependency in the dependencies {} block of the same build.gradle file
dependencies {
    // Add this dependency for desugaring java.time(kotlinx-datetime) APIs
    coreLibraryDesugaring("com.android.tools:desugar_jdk_libs:2.1.2")

    // Other dependencies...
}

iOS

The library supports various iOS architectures, including iosarm64, iossimulatorarm64, and iosx64.

To integrate this library into your iOS project using Swift Package Manager(SPM):

• Go to Xcode -> File -> Add package dependencies -> Paste below url for package -> Add package -> Done

• Add the library using Package.swift from repo - https://github.com/shivathapaa/Nepali-Date-Picker-SPM (After adding you are good to go!)

import SwiftUI
import SwiftData
import nepali_date_picker // import Nepali Date Picker library

Brief simple example usage

This library uses a 1-based index where 1 represents Sunday or January/Baisakh, 7 represents Saturday or July/Kartik, and 12 represents December/Chaitra.

Don't forget about the DateRange before using.

You can check this inside library under NepaliDatePickerDefaults.NepaliYearRange and NepaliDatePickerDefaults.EnglishYearRange

// This will be changed overtime to support wider dates.
EnglishYearRange: IntRange = IntRange(1913, 2043)
NepaliYearRange: IntRange = IntRange(1970, 2100)

Nepali Date Picker and Nepali Date Range Picker

val defaultNepaliDatePickerState = rememberNepaliDatePickerState()

NepaliDatePicker(state = defaultNepaliDatePickerState)
// NepaliDatePickerWithEnglishDate(defaultNepaliDatePickerState)

val defaultNepaliDateRangePickerState = rememberNepaliDateRangePickerState()

NepaliDateRangePicker(defaultNepaliDateRangePickerState)
// NepaliDateRangePickerWithEnglishDate(defaultNepaliDateRangePickerState)

Using directly in your main layout

// NepaliDatePicker
Column {
    NepaliDatePicker(rememberNepaliDatePickerState())
}

// NepaliDatePickerWithEnglishDate
Column {
    NepaliDatePickerWithEnglishDate(rememberNepaliDatePickerState())
}

// NepaliDateRangePicker
Column {
    NepaliDateRangePicker(rememberNepaliDateRangePickerState())
}

// NepaliDateRangePickerWithEnglishDate
Column {
    NepaliDateRangePickerWithEnglishDate(rememberNepaliDateRangePickerState())
}

Nepali Date Picker Dialog

var showNepaliDatePickerDialog by remember { mutableStateOf(false) }
val defaultNepaliDatePickerState = rememberNepaliDatePickerState() // Use separate state for each
val defaultNepaliDateRangePickerState = rememberNepaliDateRangePickerState() // Use separate state for each

// You can use provided template or use any composable you like for both confirm and dismiss button
if (showNepaliDatePickerDialog) {
    NepaliDatePickerDialog(
        confirmButton = {
            NepaliDatePickerDefaults.DialogButton(
                text = "OK",
                onButtonClick = { showNepaliDatePickerDialog = false }
            )

Using rememberNepaliDatePickerState() and rememberNepaliDateRangePickerState()

val defaultNepaliDatePickerState = rememberNepaliDatePickerState()
val defaultNepaliDateRangePickerState = rememberNepaliDateRangePickerState()

val customizedDatePickerState = rememberNepaliDatePickerState(
    initialSelectedDate = SimpleDate(2082, 2, 16),

Detailed examples to explore more

Here are some examples to help you get started. The library's documentation provides further, detailed explanations.

This library uses a 1-based index where 1 represents Sunday or January/Baisakh, 7 represents Saturday or July/Kartik, and 12 represents December/Chaitra.

Don't worry, it's not too complex! In the examples below, I've utilized various customization options to showcase multiple use cases, which might seem overwhelming. However, your specific needs may not require all of these options.

For basic use cases, refer to the section above. Or, jump into utilities.

Nepali Date Picker in main layout

// Simple use without dialog
NepaliDatePicker(rememberNepaliDatePickerState())
NepaliDatePickerWithEnglishDate(rememberNepaliDatePickerState())
NepaliDateRangePicker(rememberNepaliDateRangePickerState())
NepaliDateRangePickerWithEnglishDate(rememberNepaliDateRangePickerState())

// Defining state in variable
val datePickerState = rememberNepaliDatePickerState()
    
NepaliDatePicker(datePickerState)
// NepaliDatePickerWithEnglishDate(datePickerState)
    
val dateRangePickerState = rememberNepaliDateRangePickerState()
    
NepaliDateRangePicker(dateRangePickerState)
// NepaliDateRangePickerWithEnglishDate(dateRangePickerState)

// Customizing color
NepaliDatePicker(
    state = rememberNepaliDatePickerState(),
    colors = NepaliDatePickerDefaults.colors()
        .copy(
            containerColor = MaterialTheme.colorScheme.surfaceContainer,
            dayContentColor = MaterialTheme.colorScheme.onSurface
        )
)

Using with dialog

// Using with dialog
var showNepaliDatePickerDialog by remember { mutableStateOf(false) }
val nepaliDatePickerState = rememberNepaliDatePickerState(locale = NepaliDateLocale(language = NepaliDatePickerLang.NEPALI))

Button(onClick = { showNepaliDatePickerDialog = true }) { Text(text = "Show Dialog") }

// You can use provided template or use any composable you like for both confirm and dismiss button
if (showNepaliDatePickerDialog) {
    NepaliDatePickerDialog(
        onDismissRequest = { showNepaliDatePickerDialog = false },
        confirmButton = {
            NepaliDatePickerDefaults.DialogButton(
                text = "OK",
                onButtonClick = { showNepaliDatePickerDialog = false }
            )
        },
        dismissButton = {
            NepaliDatePickerDefaults.DialogButton(
                text = "Cancel",
                onButtonClick = { showNepaliDatePickerDialog = false }
            )
        }
    ) {
        NepaliDatePicker(state = nepaliDatePickerState)
    }
}

Using rememberNepaliDatePickerState() for different cases (similar for rememberNepaliDateRangePickerState())

// Using rememberNepaliDatePickerState() for different cases 
val todayNepaliDate = NepaliDateConverter.todayNepaliDate

// Remember that, "BeforeSelectable", "AfterSelectable", and "RangeSelectable" are helper Selectables
// that helps with enabling and disabling dates before or after today, or before or
// after certain dates, or in between certain dates, and many other use cases.
// You have full control of the dates that you want to enable or disable.

// Using Before Selectable
val customDatePickerStateWithBeforeSelectable = rememberNepaliDatePickerState(
    initialSelectedDate = SimpleDate(2080, 3, 21),
    initialDisplayedMonth = SimpleDate(2081, 1, 1),
    yearRange = IntRange(1998, 2100),
    nepaliSelectableDates = NepaliDateConverter.BeforeDateSelectable(
        simpleDate = SimpleDate(
            todayNepaliDate.year,
            todayNepaliDate.month,
            todayNepaliDate.dayOfMonth
        ), includeDate = true
    ),
    locale = NepaliDateLocale(
        language = NepaliDatePickerLang.NEPALI,
        dateFormat = NepaliDateFormatStyle.SHORT_YMD,
        weekDayName = NameFormat.MEDIUM,
        monthName = NameFormat.FULL
    )
)

// Using After selectable
val customDatePickerStateWithAfterSelectable = rememberNepaliDatePickerState(
    yearRange = IntRange(1979, 2094),
    nepaliSelectableDates = NepaliDateConverter.AfterDateSelectable(
        simpleDate = SimpleDate(
            todayNepaliDate.year, todayNepaliDate.month, todayNepaliDate.dayOfMonth
        ),
        includeDate = false
    ),
    locale = NepaliDateLocale(
        language = NepaliDatePickerLang.ENGLISH,
        dateFormat = NepaliDateFormatStyle.COMPACT_YMD,
        weekDayName = NameFormat.FULL
    )
)

// Using Range selectable
val customDatePickerStateWithRangeSelectable = rememberNepaliDatePickerState(
    initialDisplayedMonth = SimpleDate(2081, 12, 12),
    yearRange = IntRange(2079, 2090),
    nepaliSelectableDates = NepaliDateConverter.DateRangeSelectable(
        minDate = SimpleDate(
            todayNepaliDate.year, todayNepaliDate.month, todayNepaliDate.dayOfMonth
        ),
        maxDate = SimpleDate(2090, 1, 1),
        includeMinDate = false,
        includeMaxDate = true
    ),
    locale = NepaliDateLocale(
        language = NepaliDatePickerLang.ENGLISH,
        dateFormat = NepaliDateFormatStyle.COMPACT_YMD,
        weekDayName = NameFormat.FULL
    )
)

// Using your own selectable preferences
val customSelectableDatePickerState = rememberNepaliDatePickerState(
    nepaliSelectableDates = object : NepaliSelectableDates {
        override fun isSelectableDate(customCalendar: CustomCalendar): Boolean {
            return customCalendar.month != 3 || (customCalendar.dayOfWeek != 7 && customCalendar.dayOfMonth != 15)
        }

        override fun isSelectableYear(year: Int): Boolean {
            return year >= 2054
        }
    }
)

For defining state outside/inside of composition (Alternative way)

// Outside of composition (may be in viewModel, or lambdas), or inside the composition
val stateForPicker = NepaliDatePickerState(
    initialSelectedDate = SimpleDate(2081, 8, 21),
    initialDisplayedMonth = SimpleDate(2081, 7, 21),
    yearRange = IntRange(1998, 2100),
    nepaliSelectableDates = NepaliDatePickerDefaults.AllDates,
    initialDisplayMode = DisplayMode.Picker,
    locale = NepaliDatePickerDefaults.DefaultLocale
)

val stateForRangePicker = NepaliDateRangePickerState(
    initialSelectedStartNepaliDate = SimpleDate(2081, 8, 21),
    initialSelectedEndNepaliDate = SimpleDate(2081, 9, 21),
    initialDisplayedMonth = SimpleDate(2081, 7, 21),
    yearRange = IntRange(1998, 2100),
    nepaliSelectableDates = NepaliDatePickerDefaults.AllDates,
    initialDisplayMode = DisplayMode.Picker,
    locale = NepaliDatePickerDefaults.DefaultRangePickerLocale
)

NepaliDatePicker(state = stateForPicker)
NepaliDateRangePicker(state = stateForRangePicker)
