System FAQ

How do I convert time between time zones?

Select your source time zone, enter the time, then select your target time zone. The tool instantly shows the equivalent time, including automatic daylight saving time adjustments.

What is UTC and why is it used?

UTC (Coordinated Universal Time) is the primary time standard used globally. It doesn't change for daylight saving. All time zones are expressed as UTC+ or UTC- offsets. New York is UTC-5 (EST) or UTC-4 (EDT).

How do I find the best meeting time for a global team?

Use the meeting planner: enter times during business hours in your time zone and see what time it is for team members in other zones. Aim for overlap in standard business hours (9am-5pm) for all participants.

How does daylight saving time affect time zone conversions?

Daylight Saving Time (DST) shifts the clock forward 1 hour in spring and back in fall. Not all countries observe DST, and they change on different dates. This tool automatically accounts for current DST status in each time zone.

What time zones does the US have?

The contiguous US has 4 time zones: Eastern (ET, UTC-5/4), Central (CT, UTC-6/5), Mountain (MT, UTC-7/6), and Pacific (PT, UTC-8/7). Hawaii is UTC-10, Alaska is UTC-9. Numbers in parentheses show Standard/Daylight Saving Time offsets.
