[日期时间] 批处理如何获取当前日期的后一天日期（即明天的日期）？

@echo off
rem 计算指定天数之前的日期
set DaysAgo=-1
rem 假设系统日期的格式为yyyy-mm-dd
call :DateToDays %date:~0,4% %date:~5,2% %date:~8,2% PassDays
set /a PassDays-=%DaysAgo%
call :DaysToDate %PassDays% DstYear DstMonth DstDay
set DstDate=%DstYear%-%DstMonth%-%DstDay%
call :weekdays %DaysAgo% 
echo %DaysAgo%天的日期是%DstDate% %week%
