About this tool
This page opens the date calculator with 180 days already set to be added to today — the exact half-year-out date is on screen the moment the page loads.
The 180-day mark matters in travel and law: many countries require passports valid for six months beyond entry, visa rules cap stays within rolling 180-day windows, and half a year is a standard horizon for medical follow-ups and financial terms. Since 180 days is not exactly six calendar months, the true date is worth checking.
Need a different span or direction? The full tool adds or subtracts any number of days, weeks, months, or years from any date, entirely 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.
