HOW to find last SUNDAY DATE through batch

问题

How to find 'last SUNDAY DATE' through batch command? what I was trying is

echo %date:~4,2%%date:~7,2%%date:~10,4%

this is good for current date but for last Sunday date... can anyone suggest any logic through batch.

回答1:

Windows PowerShell:

[DateTime]::Now.AddDays(-1 * [DateTime]::Now.DayOfWeek.value__)

Sorry the environment variable %date% in Batch (.bat) files sounds uneasy to do calculations.
