Why Add More Days to a Date?
Adding days to a date is one of the most common practical calculations: when does a 30-day return window expire? What date is 90 days after signing a contract? When is the project deadline if work starts today and lasts 45 days? Instead of counting manually on a calendar, this free tool gives you the answer in under a second.
How the Add Days Calculator Works
Select a start date, enter the number of days to add (any positive integer), and click Calculate. The calculator adds the exact number of calendar days, correctly handling months with 28, 29, 30 or 31 days and leap years. The result date is shown in a clear format so you can use it right away.
Examples: Adding Days to Common Dates
Today + 7 days = same day next week. Today + 14 days = two weeks from today. Today + 30 days = roughly one month ahead. Today + 90 days = roughly three months ahead. Today + 365 days = one year from today (or 366 in a leap year). Use the calculator above for the exact date.
