Installation 📦

pip install datepulator

Quick Start 🚀

from datepulator import DateManager

# Initialize DateManager
dm = DateManager(default_timezone="UTC")

# Convert date format
result = dm.convert("2023/12/25", from_format="%Y/%m/%d", to_format="%d-%b-%Y")
print(result)  # Output: 25-Dec-2023

# Add time to a date
new_date = dm.add_time("2023-01-15", 
                       years=1, 
                       months=2, 
                       days=10)
print(new_date)  # Output: 2024-03-25T00:00:00

# Calculate age
age = dm.calculate_age("1990-05-20")
print(age)  # Output: {'years': 33, 'months': 7, 'days': 15, 'total_days': 12271}

Detailed Usage 📚

1. Date Arithmetic

dm = DateManager()

# Add time
future_date = dm.add_time("2023-01-15",
                         years=1,
                         months=2,
                         days=3,
                         hours=4,
                         minutes=30)

# Subtract time
past_date = dm.subtract_time("2023-01-15",
                           months=3,
                           days=5)

2. Timezone Conversions

# Convert from UTC to New York time
ny_time = dm.convert_timezone("2023-01-15 10:00:00",
                            from_tz="UTC",
                            to_tz="America/New_York")

# Convert from Tokyo to London time
london_time = dm.convert_timezone("2023-01-15 15:00:00",
                                from_tz="Asia/Tokyo",
                                to_tz="Europe/London")

3. Business Days

# Define holidays
holidays = [
    "2023-12-25",  # Christmas
    "2023-12-26",  # Boxing Day
    "2024-01-01"   # New Year's Day
]

# Check if it's a business day
is_working = dm.is_business_day("2023-12-25", holidays=holidays)

# Add business days
next_working_day = dm.add_business_days("2023-12-24", 
                                      days=3,
                                      holidays=holidays)

4. Date Ranges

# Get daily dates
daily_dates = dm.get_date_range("2023-01-01",
                               "2023-01-10",
                               interval="days")

# Get weekly dates
weekly_dates = dm.get_date_range("2023-01-01",
                                "2023-03-01",
                                interval="weeks")

# Get monthly dates
monthly_dates = dm.get_date_range("2023-01-01",
                                 "2023-12-31",
                                 interval="months")

5. Age Calculation

# Calculate age as of today
current_age = dm.calculate_age("1990-05-20")

# Calculate age as of a specific date
past_age = dm.calculate_age("1990-05-20", 
                          reference_date="2010-01-01")
