About this tool
This page opens the date calculator set to add 90 days to today — the exact end date of the 90-day window is visible as soon as the page loads.
Ninety days is the classic quarter-length term: probation periods at new jobs, 90-day visa-free stays, prescription refills, money-back guarantees, and quarterly business reviews all run on it. The end date shifts with month lengths, so a real day count beats “three months from now” guesswork.
If your term is different, the full tool takes any amount — days, weeks, months, or years, added or subtracted from any base date — and calculates it locally in your browser.
Example. 31 January 2024 plus 1 month is Thursday 29 February 2024. 29 February 2024 plus 1 year is Friday 28 February 2025. 1 January 2026 plus 45 days is Sunday 15 February 2026.
Limit. The amount must be an integer. Months and years clamp to the last real day. The math is a UTC calendar date, not a timestamp and not a holiday calendar.
