Frequently Asked Questions
1. How many time zones are there in the world?
There are 24 standard time zones (one for each hour of the day), plus several offset time zones (e.g., India UTC+5:30, Nepal UTC+5:45, Newfoundland UTC-3:30). Total official time zones: approximately 38.
2. What is UTC?
UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks and time. It's the successor to GMT (Greenwich Mean Time). All time zones are expressed as offsets from UTC (e.g., UTC+5:30 for Sri Lanka/India).
3. Why do some countries have 30-minute or 45-minute offsets?
Historical and political reasons. India chose UTC+5:30 to split the difference between its western and eastern borders. Nepal chose UTC+5:45, and some Australian territories use UTC+10:30.
4. What is Daylight Saving Time (DST)?
DST advances clocks by one hour during summer months to extend evening daylight. Not all countries observe DST. Our world clock adjusts automatically for DST where applicable.
5. Does the world clock work offline?
Once the page loads, the clock uses your device's system time and continues updating locally. However, time zone data requires internet to load initially.
6. Is my location data stored or tracked?
Absolutely not. Your local time is determined by your browser's system clock — no location data is ever sent to our servers. Complete privacy guaranteed.
7. What's the best time to schedule international meetings?
Aim for 8 AM - 6 PM in both locations. For US-Asia calls, this often means early morning US or late evening Asia. Use our time comparison tool to find overlapping business hours.
