## Now
Now is a time toolkit for golang
[![go report card](https://goreportcard.com/badge/github.com/jinzhu/now "go report card")](https://goreportcard.com/report/github.com/jinzhu/now)
[![test status](https://github.com/jinzhu/now/workflows/tests/badge.svg?branch=master "test status")](https://github.com/jinzhu/now/actions)
[![MIT license](https://img.shields.io/badge/license-MIT-brightgreen.svg)](https://opensource.org/licenses/MIT)
## Install
```
go get -u github.com/jinzhu/now
```
## Usage
Calculating time based on current time
```go
import "github.com/jinzhu/now"
time.Now() // 2013-11-18 17:51:49.123456789 Mon
now.BeginningOfMinute() // 2013-11-18 17:51:00 Mon
now.BeginningOfHour() // 2013-11-18 17:00:00 Mon
now.BeginningOfDay() // 2013-11-18 00:00:00 Mon
now.BeginningOfWeek() // 2013-11-17 00:00:00 Sun
now.BeginningOfMonth() // 2013-11-01 00:00:00 Fri
now.BeginningOfQuarter() // 2013-10-01 00:00:00 Tue
now.BeginningOfYear() // 2013-01-01 00:00:00 Tue
now.EndOfMinute() // 2013-11-18 17:51:59.999999999 Mon
now.EndOfHour() // 2013-11-18 17:59:59.999999999 Mon
now.EndOfDay() // 2013-11-18 23:59:59.999999999 Mon
now.EndOfWeek() // 2013-11-23 23:59:59.999999999 Sat
now.EndOfMonth() // 2013-11-30 23:59:59.999999999 Sat
now.EndOfQuarter() // 2013-12-31 23:59:59.999999999 Tue
now.EndOfYear() // 2013-12-31 23:59:59.999999999 Tue
now.WeekStartDay = time.Monday // Set Monday as first day, default is Sunday
now.EndOfWeek() // 2013-11-24 23:59:59.999999999 Sun
```
Calculating time based on another time
```go
t := time.Date(2013, 02, 18, 17, 51, 49, 123456789, time.Now().Location())
now.With(t).EndOfMonth() // 2013-02-28 23:59:59.999999999 Thu
```
Calculating time based on configuration
```go
location, err := time.LoadLocation("Asia/Shanghai")
myConfig := &now.Config{
WeekStartDay: time.Monday,
TimeLocation: location,
TimeFormats: []string{"2006-01-02 15:04:05"},
}
t := time.Date(2013, 11, 18, 17, 51, 49, 123456789, time.Now().Location()) // // 2013-11-18 17:51:49.123456789 Mon
myConfig.With(t).BeginningOfWeek() // 2013-11-18 00:00:00 Mon
myConfig.Parse("2002-10-12 22:14:01") // 2002-10-12 22:14:01
myConfig.Parse("2002-10-12 22:14") // returns error 'can't parse string as time: 2002-10-12 22:14'
```
### Monday/Sunday
Don't be bothered with the `WeekStartDay` setting, you can use `Monday`, `Sunday`
```go
now.Monday() // 2013-11-18 00:00:00 Mon
now.Monday("17:44") // 2013-11-18 17:44:00 Mon
now.Sunday() // 2013-11-24 00:00:00 Sun (Next Sunday)
now.Sunday("18:19:24") // 2013-11-24 18:19:24 Sun (Next Sunday)
now.EndOfSunday() // 2013-11-24 23:59:59.999999999 Sun (End of next Sunday)
t := time.Date(2013, 11, 24, 17, 51, 49, 123456789, time.Now().Location()) // 2013-11-24 17:51:49.123456789 Sun
now.With(t).Monday() // 2013-11-18 00:00:00 Mon (Last Monday if today is Sunday)
now.With(t).Monday("17:44") // 2013-11-18 17:44:00 Mon (Last Monday if today is Sunday)
now.With(t).Sunday() // 2013-11-24 00:00:00 Sun (Beginning Of Today if today is Sunday)
now.With(t).Sunday("18:19:24") // 2013-11-24 18:19:24 Sun (Beginning Of Today if today is Sunday)
now.With(t).EndOfSunday() // 2013-11-24 23:59:59.999999999 Sun (End of Today if today is Sunday)
```
### Parse String to Time
```go
time.Now() // 2013-11-18 17:51:49.123456789 Mon
// Parse(string) (time.Time, error)
t, err := now.Parse("2017") // 2017-01-01 00:00:00, nil
t, err := now.Parse("2017-10") // 2017-10-01 00:00:00, nil
t, err := now.Parse("2017-10-13") // 2017-10-13 00:00:00, nil
t, err := now.Parse("1999-12-12 12") // 1999-12-12 12:00:00, nil
t, err := now.Parse("1999-12-12 12:20") // 1999-12-12 12:20:00, nil
t, err := now.Parse("1999-12-12 12:20:21") // 1999-12-12 12:20:21, nil
t, err := now.Parse("10-13") // 2013-10-13 00:00:00, nil
t, err := now.Parse("12:20") // 2013-11-18 12:20:00, nil
t, err := now.Parse("12:20:13") // 2013-11-18 12:20:13, nil
t, err := now.Parse("14") // 2013-11-18 14:00:00, nil
t, err := now.Parse("99:99") // 2013-11-18 12:20:00, Can't parse string as time: 99:99
// MustParse must parse string to time or it will panic
now.MustParse("2013-01-13") // 2013-01-13 00:00:00
now.MustParse("02-17") // 2013-02-17 00:00:00
now.MustParse("2-17") // 2013-02-17 00:00:00
now.MustParse("8") // 2013-11-18 08:00:00
now.MustParse("2002-10-12 22:14") // 2002-10-12 22:14:00
now.MustParse("99:99") // panic: Can't parse string as time: 99:99
```
Extend `now` to support more formats is quite easy, just update `now.TimeFormats` with other time layouts, e.g:
```go
now.TimeFormats = append(now.TimeFormats, "02 Jan 2006 15:04")
```
Please send me pull requests if you want a format to be supported officially
