How it works
30 days from today means counting forward 30 calendar days starting tomorrow. That is 4 weeks and 2 days. The date at the top updates to your device's own date, so it is right whenever you open this page.
Pick a start date (today by default) and a number of days. The calculator moves forward on the calendar one day at a time, so month lengths and leap years (like February 29, 2028) are handled for you. Choose Before to count backward, for example "90 days ago".
With Business days, Saturdays and Sundays are skipped. Public holidays are not skipped, so check those yourself for legal or shipping deadlines.
End date = start date + N days (day 1 is the day after the start date)
Worked example
From Thursday, October 22, 2026, 30 days later is Saturday, November 21, 2026, and 30 days earlier was Tuesday, September 22, 2026.
