java - 减去两天并只计算工作日(没有周六或周日)

Question

我正在寻找能够提供以下能力的外部 JAR 或方法:

1. 减去两个日期。
2. 将节假日定义为周六和周日，或周五和周六。
3. 计算有无假期的差异。

在我进行公历计算之前，任何人都可以推荐一个外部 JAR 吗？

Answer 1

看看at this site ，他们为您提供了一个 Java 程序来帮助您:

The wdnum() method returns the number of weekdays (excluding weekends) that have passed since Monday, 29 December 1969. It works by calculating the number of days since 1 January, 1970 (getTime() divided by the number of milliseconds in a day), adding 3 and returning the number of week days in full weeks and possibly a partial week that have passed since then.
