go 本周周一的获取

time.Weekday类型可以做运算，强制转int,会得到偏差数。默认是 Sunday 开始到 Saturday 算 0,1,2,3,4,5,6所以只有Monday减去Sunday的时候是正数，特殊处理下就可以了。package dateimport ( “fmt” “time”)func WeekDayTest() { now := time.Now() offset := int(time.Monday - now.Weekday()) if offset > 0 { offset = -6 } weekStart := time.Date(now.Year(), now.Month(), now.Day(), 0, 0, 0, 0, time.Local).AddDate(0, 0, offset) fmt.Println(weekStart)}
