Instantly see the current local time in any city worldwide. NovaTimezone covers 40+ major cities across all time zones including EST, CST, MST, PST for the USA, and hundreds of cities in Europe, Asia, Africa, and the Americas. All times update live every second and automatically account for Daylight Saving Time (DST).
Search "New York" in the timezone converter above to see the current Eastern Time (ET), including whether DST is currently active.
There are 24 standard time zones, but the actual number of UTC offsets used worldwide is around 38-40 when you include half-hour and quarter-hour offsets like India (UTC+5:30) and Nepal (UTC+5:45).
EST (Eastern Standard Time) is UTC-5, used in winter. EDT (Eastern Daylight Time) is UTC-4, used during Daylight Saving Time in summer. Most references to "Eastern Time" cover both and switch automatically.
Milliseconds:
The Unix timestamp (also called epoch time) is the number of seconds since January 1, 1970 at 00:00:00 UTC. It is the standard time format used by databases, APIs, programming languages and server logs. Use this tool to convert any Unix timestamp to a human-readable date, or to look up the current epoch time in both seconds and milliseconds.
Find the exact sunrise, sunset, solar noon, golden hour, and civil twilight times for any city in the world. Simply type your city name or ZIP code and select a date. Data is sourced from Open-Meteo, the free and open-source weather API, ensuring accuracy to the minute for any location on Earth.
Golden hour is the period shortly after sunrise and before sunset when sunlight is softer, warmer and more directional. It typically lasts about 30-60 minutes and produces beautiful, diffused light for photography.
Civil twilight is the period before sunrise and after sunset when there is still enough natural light to see without artificial lighting. It ends when the sun is 6 degrees below the horizon.
See the current moon phase with precise illumination percentage and a visual representation of the moon. NovaTimezone calculates moon phases using the known synodic cycle of 29.53 days from a reference new moon. Find out exactly when the next full moon, new moon, first quarter and last quarter will occur.
One complete lunar cycle (synodic month) takes approximately 29 days, 12 hours, 44 minutes and 3 seconds — commonly rounded to 29.53 days.
The moon phase affects ocean tides most significantly. Many cultures and traditions also track moon phases for planting, fishing, and spiritual practices. The full moon is the brightest phase, making it less ideal for stargazing.
Plan meetings and calls with people in different time zones. Select up to 5 cities and a proposed meeting time to instantly see what time it will be for each participant. Color-coded indicators show green for business hours, amber for early/late, and red for sleeping hours, making it easy to find a time that works for everyone globally.
India (IST, UTC+5:30) is 10.5 hours ahead of Eastern Time. A 7:30 AM EST meeting is 6 PM IST — a good overlap. Try the meeting planner above to find your ideal time.

Useful for international business planning, travel scheduling, and staying informed about your friends' and colleagues' local holidays.
Select "United States" from the dropdown above to see all 11 US federal holidays with exact dates and days remaining for the current year.
Yes. Fixed holidays (Christmas, Independence Day etc.) are exact. Floating holidays like Thanksgiving or Easter are calculated algorithmically for the current year using standard formulas.
