About this tool
This page opens the calculator preloaded with “add 120 days” from today — the precise resulting date, weekday included, is displayed right away.
A 120-day span — roughly four months — appears in extended payment terms (net-120), long procurement and manufacturing lead times, planning windows for events, and some regulatory filing periods. Spanning four different month lengths, it is genuinely awkward to count by hand.
For any other horizon, the full tool adds or subtracts whatever amount you need in days, weeks, months, or years, from any starting date — computed 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.
