- DateTime.parse('2021-05-01T10:30:30.000Z').diff("2021-04-30T10:30:30.000Z") why is 0+1/365
dayjs is 0+1/30/12 see dayjs
in my opinion, 2021-03-01 is one year and 28 days more than 2020-02-01. It can be disassembled into 2021-02-01 which is one year more than 2020-02-01. In addition, 2021-03-01 is 28 days more than 2021-02-01
在我看来, 2021-03-01 比 2020-02-01 多了 1年零28天 ，可以拆解为 2021-02-01比2020-02-01多了1年，加上2021-03-01比2021-02-01多了28天。
