FAQs

How many time zones are there in the world?

There are 24 standard time zones (one per hour). However, actual time zones number 38+ due to half-hour and 45-minute offsets (India: UTC+5:30, Nepal: UTC+5:45). Some countries span multiple zones - Russia has 11!

What is UTC and GMT?

UTC (Coordinated Universal Time) is the global time standard. GMT (Greenwich Mean Time) is UTC+0 timezone. They're essentially the same, but UTC is the modern scientific standard. All time zones are defined as +/- hours from UTC.

When does Daylight Saving Time change?

In US/Canada: Spring forward 2nd Sunday in March, Fall back 1st Sunday in November. Europe: Last Sunday in March and October. Not all countries observe DST. Arizona, Hawaii, and most of Asia don't change clocks.

How do I schedule meetings across time zones?

Best practices: use UTC for reference, consider work hours (9 AM-5 PM) in all zones, rotate meeting times to share burden, use tools like World Time Buddy, state timezone clearly ("9 AM ET"), and record meetings for those who can't attend live.

What is the International Date Line?

The International Date Line runs through the Pacific Ocean at roughly 180° longitude. Crossing westward, you skip forward one day. Crossing eastward, you go back one day. This prevents time zone confusion - ensures whole world stays within one calendar day.

Which time zone should I use for global teams?

Options: UTC (neutral, no DST), EST/PST (if US-heavy team), compromise zone (if Europe-Asia split). Many global companies use UTC for documentation and let individuals convert to local time. Avoid assuming everyone knows your timezone.
