A simple extension for Time based on PHP's Carbon library.


  • Time is embedded into Carbon (provides access to all of Time's functionality)
  • Supports addition and subtraction of dates
  • Provides methods to compare dates
  • Supports date formatting in common formats
  • Easily calculate difference between dates
  • Ease testing with dates by using carbon.Freeze() and carbon.Now()

To do:

  • Implement all localization features as in Carbon
  • Improve the code style to be more idiomatic Go

Getting started

Install Carbon:

go get

Add to your imports to start using Carbon

import ""


A simple example to get you started:

package main

import (


func main() {
	fmt.Printf("Right now is %s\n", carbon.Now().DateTimeString())

	today, _ := carbon.NowInLocation("America/Vancouver")
	fmt.Printf("Right now in Vancouver is %s\n", today)

	fmt.Printf("Tomorrow is %s\n", carbon.Now().AddDay())
	fmt.Printf("Last week is %s\n", carbon.Now().SubWeek())

	nextOlympics, _ := carbon.CreateFromDate(2016, time.August, 5, "Europe/London")
	nextOlympics = nextOlympics.AddYears(4)
	fmt.Printf("Next olympics are in %d\n", nextOlympics.Year())

	if carbon.Now().IsWeekend() {
		fmt.Printf("Party time!")
