Period.between介绍

[英]Obtains a Period consisting of the number of years, months, and days between two dates.

The start date is included, but the end date is not. The period is calculated by removing complete months, then calculating the remaining number of days, adjusting to ensure that both have the same sign. The number of months is then split into years and months based on a 12 month year. A month is considered if the end day-of-month is greater than or equal to the start day-of-month. For example, from 2010-01-15 to 2011-03-18 is one year, two months and three days.

The result of this method can be a negative period if the end is before the start. The negative sign will be the same in each of year, month and day.
[中]获取由两个日期之间的年、月和日数组成的期间。
包括开始日期，但不包括结束日期。计算周期的方法是删除完整的月份，然后计算剩余的天数，并进行调整以确保两者具有相同的符号。然后根据12个月的年份将月数分为年和月。如果一个月的结束日大于或等于该月的开始日，则视为一个月。例如，从2010-01-15到2011-03-18是一年零两个月零三天。
如果结束时间早于开始时间，则此方法的结果可能是负周期。负号在每年、每月和每天都是相同的。
