About this tool
This page opens the date calculator already set to add 30 days to today — the exact resulting date, including the weekday, is displayed the moment the page loads.
Thirty days is one of the most common deadlines in paperwork: net-30 invoices fall due, 30-day return windows close, and many rental agreements and subscriptions require 30 days’ notice. Counting it on a calendar invites off-by-one mistakes; the calculator lands on the precise date every time.
Need something else? The full tool adds or subtracts any number of days, weeks, months, or years from any base date — and the whole calculation runs 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.
