date.isocalendar() method is used to manipulate objects of date class of module datetime.
date.isocalendar()方法用于操作模块datetime的日期类的对象。
It uses a date class object and returns a 3-tuple (ISO year, ISO week number, ISO weekday).
它使用日期类对象并返回一个三元组(ISO年,ISO周号,ISO周日)。
Most of the date and time calendar follow the Gregorian calendar. The ISO calendar is a widely used variant of the Gregorian one. The ISO year consists of 52 or 53 full weeks, and where a week starts on a Monday and ends on a Sunday. The first week of an ISO year is the first (Gregorian) calendar week of a year containing a Thursday. This is called week number 1, and the ISO year of that Thursday is the same as its Gregorian year.
For example, 2004 begins on a Thursday, so the first week of ISO year 2004 begins on Monday, 29 Dec 2003 and ends on Sunday, 4 Jan 2004:大多数日期和时间日历都遵循公历。 ISO日历是公历之一的广泛使用的变体。 ISO年度包括52或53个整周,其中一个星期从星期一开始,在星期日结束。 ISO年的第一周是包含星期四的一年中的第一个(格里高利历)日历周。 这称为第1周,该周四的ISO年与其公历年相同。
例如,2004年从星期四开始,因此ISO 2004年的第一周从2003年12月29日星期一开始,到2004年1月4日星期日结束:Weekday number for Monday is 1 while incrementing by 1 for the coming days.
星期一的工作日数为1,而接下来的几天则增加1。
