How 30 days ago is counted
Today counts as day zero and every calendar day after it counts as one, weekends included. So the answer is simply today's date minus 30 days. People most often look this up for 30-day return windows, a 30-day notice period on a lease, and 30-day payment terms.
Need a different number? The add or subtract days tool takes any figure, and the countdown calendar works the other way — pick a date and see how far away it is.
