Frequently Asked Questions

How does Daylight Saving Time affect conversions?

This tool uses the Intl.DateTimeFormat API which automatically applies DST rules for each time zone based on the selected date. You don't need to manually adjust for DST — it's handled automatically based on the current DST schedule for each region.

What time zones are supported?

We support all IANA time zones — over 400 zones including UTC offsets, major city zones (America/New_York, Europe/London, Asia/Tokyo), and regional zones. The world clock includes the 20 most common global cities by default.

What is UTC and why is it the standard?

UTC (Coordinated Universal Time) is the primary time standard for the world. It doesn't observe DST and serves as the reference point from which all time zones are offset (e.g., New York is UTC-5, London is UTC+0, Tokyo is UTC+9). UTC replaced GMT as the international standard in 1972.

What is the Meeting Planner for?

The Meeting Planner shows your chosen time across 8 major world cities simultaneously — color-coded to show which times are within business hours (9am–6pm) in each location. This helps you find a meeting time that works across multiple continents.

📺 Live events

👥 Remote teams

Coordinate daily standups, deadlines, and deliveries across team members in different countries without the constant mental arithmetic of timezone math.

The world is divided into 24 primary time zones, offset from UTC (Coordinated Universal Time) by whole or half hours. Some countries like India (UTC+5:30) and Nepal (UTC+5:45) use non-standard offsets. Daylight Saving Time (DST) adds further complexity by shifting clocks seasonally in many countries — making a reliable converter essential.
