Microsoft Excel 错误地假定 1900 年是闰年。 本文解释了为什么将 1900 年视为闰年,并概述了更正此特定问题时可能发生的行为。 更多信息 当Lotus 1-2-3 首次发布时,该计划假定 1900 年是闰年,尽管它实际上不是闰年。 这使得程序更容易处理闰年,并且不会对 Lotus 1-2-3 中的几乎所有日期计算造成伤害。

You need to enter a start date in A4 and an end date in B4. Use a format such as 2/17/1865 when entering dates. If your date is after 1900, Excel automatically converts the date to a date serial number. If the date is before 1900, Excel stores the date as text. If the cell ...

1、打开Excel，在A1、B1、C1三个横向单元格中分别输入“当前日期”、“持续月数”和“到期时间”。2、将鼠标放在C2(第三列，第二行）单元格，然后点击插入函数"fx"。3、在搜索函数框里面输入“date”，然后点击搜索到的DATE函数后并点击确定。4、在函数参数设置中设置好DATE函数的参数值后点击确定。
Excel does not work with dates before 1900. These dates are recorded as text. Therefore, it is not possible to apply the date format to them. To find the difference between dates before 1900, it is recommended to add 2000 years to each of them. You can use something like this: =DATEDI...
Date Limitation: Excel recognizes dates only on or after January 1, 1900. Dates before this starting point are not valid and may require special workarounds if handling years between 1 and 1899. Number Format vs. Value: Changing the number format of a date in Excel does not alter the unde...
If you pre-format a range of cells as text, you can enter all dates as yyyy-mm-dd, including dates before 1900-01-01 (Or 1904-01-02 if you use the 1904 date system). This facilitates the subsequent sorting of the dates into date order. If you do not pre-format the dates as tex...
