How to Calculate the Date 30 Days Ago
You can figure out the date thirty days ago by hand using a calendar. Look at the calendar and look backward one day at a time while also subtracting one from 30 for each day you look backward.
You can also move backward one week at a time while subtracting seven from 30 for each week you look backward.
Continue this process until your original number has reached zero after subtracting the days. This is the date 30 days ago.
You can use a tool such as our day counter to simplify this process.
