  with:
    args: date +%F

- uses: ajilraju/[email protected]
  with: date --date='2 days ago'

- uses: ajilraju/[email protected]
  with: date -d 1may '+%B %-d'

• To print the date of the day before yesterday:

date --date='2 days ago'

• To print the date of the day three months and one day hence:

date --date='3 months 1 day'

• To print the day of year of Christmas in the current year:

date --date='25 Dec' +%j

• To print the current full month name and the day of the month:

date '+%B %d'

But this may not be what you want because for the first nine days of the month, the ‘%d’ expands to a zero-padded two-digit field, for example ‘date -d 1may '+%B %d'’ will print ‘May 01’.

• To print a date without the leading zero for one-digit days of the month, you can use the (GNU extension) ‘-’ flag to suppress the padding altogether:

date -d 1may '+%B %-d'

• To print the current date and time in the format required by many non-GNU versions of date when setting the system clock:

date +%m%d%H%M%Y.%S

• To set the system clock forward by two minutes:

date --set='+2 minutes'
