Another way (credit):
@For /F "tokens=2,3,4 delims=/ " %%A in ('Date /t') do @(
Set Month=%%A
Set Day=%%B
Set Year=%%C
)
@echo DAY = %Day%
@echo Month = %Month%
@echo Year = %Year%
Note that both my answers here are still reliant on the order of the day and month as determined by regional settings - not sure how to work around that.
