Add Days to Date
Calculate the resulting date when adding N days to a start date. Instant result with correct leap year handling.
How does it work?
Day addition runs the math in UTC, which sidesteps daylight saving time errors. As for leap years, JavaScript takes care of those on its own.
Add days to a date
What date falls 90 days from now? And the final deadline of a contract due in 45 days? Counting that on the calendar is where almost everyone slips, all the more when the span crosses months or a leap year. The tool adds a number of days to a start date and shows where it lands.
Month and year rollovers, months of different lengths, leap years: it handles all of that on its own and returns the exact date. It serves to calculate deadlines, due dates, delivery dates, the end of a warranty or any forward count from a date.
Enter the start date and the days to add; the final date appears right after. The calculation is immediate, runs in the browser and stores nothing.
