What we do
What Date Today is a free, no-login web tool that answers one of the most common questions on the internet: what is today's date?
We answer that question across 14+ different calendar systems — Gregorian, Islamic Hijri, Hebrew, Persian Solar Hijri, Ethiopian, Coptic, Chinese, Mayan, French Republican, Julian, and more. We also provide:
- Live calendar widgets showing today's date in every major calendar
- Calendar converters — between Hijri, Persian, Hebrew, and Gregorian calendars
- Holiday countdowns — for Christmas, Eid, Diwali, Chinese New Year, and more
- Year calendars — full 12-month grids for Gregorian, Hijri, and Persian years
- Date utilities — leap year checker, day of the year, week number, Unix timestamp, and more
Why we built it
The web has many calendar tools, but most fall into one of two camps:
- Single-calendar pages that don't acknowledge the world has dozens of calendar systems in active use
- Bloated calendar apps that are slow, ad-heavy, and require accounts
We wanted something different: a fast, lightweight, multi-calendar tool that just works. No accounts. No popups. No tracking beyond standard analytics. Just the dates you need, instantly.
Our calendar accuracy
We take date accuracy seriously. Our conversions are based on widely accepted calendar algorithms:
- Islamic Hijri — tabular Islamic calendar (Kuwaiti algorithm), the international standard
- Hebrew — Maimonides' standard arithmetic Hebrew calendar
- Persian — 33-year leap cycle algorithm matching the Iranian government's official calendar
- Ethiopian and Coptic — based on the Alexandrian calendar tradition
- Mayan Long Count — matching the Maya Calendar Conversion Tool (MCCT) standard
- French Republican — using the Romme rule (since the original astronomical version is no longer used)
Where local moon-sighting differs from calculated dates (Islamic and some Hebrew dates), we note this prominently.
What we don't do
- We don't require sign-ups or store user data without consent
- We don't display intrusive popups, autoplay video ads, or interstitials
- We don't share your data with anyone except as required for analytics and advertising (with your consent)
- We don't make claims about religious observance — Hajj, Eid, and Ramadan dates depend on local moon sighting and we always reflect that
