Calendar

The Calendar package is implemented based on the Go time package and aims to increase the calendar functions of the time package.

The Calendar package can generate weekly, monthly, and annual calendars based on any point in time.

Install

go get -u github.com/cmzz/calendar

Example

Annual calendar

year := NewYear(time.Date(2018, time.January, 1, 0, 0, 0, 0, time.UTC))
year.SetDayFormat("02")
year.SetDateFormat("2006-01-02")

year.InitDays()
year.InitMonth()

fmt.Println(fmt.Sprintf("%d 年年历", year.Start().NYear()))
year.Print()

Output:
