- What's today's date?
- Today's date in your timezone is shown in the live clock at the top of this page. The page also displays the same moment in 12 different calendar systems — Gregorian, ISO 8601, Julian Day Number, Unix timestamp, Hijri Islamic, Hebrew, Chinese lunar, Japanese Reiwa, Thai Buddhist, and Hindu Vikram Samvat — so you can pick whichever format you need.
- How do I find today's date if my computer's clock is wrong?
- This page reads the date from your browser, which gets it from your operating system. If your OS clock is off, the date shown will be off too. To verify against an authoritative source, open our Exact Time tool, which compares your device clock to NTP-synchronized servers and shows the drift in milliseconds.
- What is the Julian Day Number?
- The Julian Day Number (JDN) is a continuous count of days since November 24, 4713 BCE in the proleptic Gregorian calendar (or January 1, 4713 BCE Julian). Astronomers use it because it has no months, no leap-year exceptions, and no calendar reform discontinuities — every day is just an integer. Today's JDN is shown in the table above.
- What's the difference between Gregorian and ISO 8601 dates?
- Gregorian is the everyday calendar (April 28, 2026). ISO 8601 is a numeric, internationally unambiguous format (2026-04-28) that sorts correctly as a string and never mixes up day-month order. ISO 8601 also defines a week date (2026-W18-2 = Tuesday of week 18, 2026), which is what spreadsheets and many APIs use for fiscal weeks.
- Why is the Hijri (Islamic) date here different from what my mosque shows?
- The Islamic calendar is observational — Saudi Arabia's Umm al-Qura authority, regional moon-sighting committees, and the Islamic Society of North America (ISNA) all publish slightly different month-start dates, often differing by ±1 day. We show the Umm al-Qura tabular variant, which is the one most platforms (iOS, Android, Windows) use as their default. Local prayer times and Ramadan dates may vary.
- What year is it in the Chinese calendar?
- The Chinese lunar calendar uses two parallel year encodings. The cycle position (1 to 60, sexagenary) is what most apps display. The continuous count from the legendary reign of the Yellow Emperor (2697 BCE) gives a year in the 47xx range — that's what we show. The current zodiac animal is also displayed.
- Is the Hindu Vikram Samvat date here exact?
- It's an approximation. We compute the Vikram year (Gregorian + 56 or +57 depending on whether the date is before or after mid-April) and rotate the month name based on the solar wheel, but the page does not run full panchanga (tithi/paksha) math. For prayer-grade dates, look up a panchang for your location.
