How 45 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 45 days. People most often look this up for 45-day payment terms and many 45-day return or trial windows.
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.
