How it works

Enter a time in one timezone and instantly see what time it is in multiple other timezones around the world. The converter handles daylight saving time automatically.

Add as many cities or timezones as you need. The tool shows all times side-by-side so you can find overlapping hours for meetings or calls.

Example conversion:

Input: 9:00 AM Monday, New York (EST) Output: New York: 9:00 AM Monday London: 2:00 PM Monday Tokyo: 11:00 PM Monday Sydney: 1:00 AM Tuesday Los Angeles: 6:00 AM Monday

The converter shows the day of week for each timezone. A morning meeting in the US might be late evening or even the next day in Asia and Australia.

When You'd Actually Use This

Global team standups

A scrum team has members in San Francisco, London, and Bangalore. The converter shows 9 AM PST is 5 PM GMT and 10:30 PM IST. They rotate meeting times weekly to share the inconvenience.

International conference calls

Quarterly business reviews include executives from 5 continents. The converter helps find the rare 2-hour window when it's business hours for New York, London, and Singapore simultaneously.

Software release coordination

DevOps teams coordinate deployments across regions. A release at 2 AM UTC means 9 AM in Sydney, 10 PM previous day in New York. The converter ensures all teams know their local time.

Live broadcast scheduling

A company announces a product launch at 10 AM Pacific Time. The converter shows it's 1 PM Eastern, 6 PM in London, 2 AM next day in Sydney - helping viewers worldwide know when to tune in.

Customer support handoffs

Support teams in Manila, Dublin, and Phoenix pass tickets between shifts. The converter shows when shifts overlap for handoff meetings and ensures 24/7 coverage without gaps.

Online class scheduling

An instructor teaches students from 15 countries. The converter helps find times that don't require anyone to attend at 3 AM. Sometimes two sessions are needed for different regions.

What to Know Before Using

Daylight saving transitions happen on different dates.The US switches DST in March and November, Europe in March and October. Between these dates, the time difference temporarily changes by an hour. Always verify dates around transition periods.

Some timezones have half-hour offsets.India is UTC+5:30, Nepal is UTC+5:45, and the Chatham Islands are UTC+12:45. When converting, you'll see times like 9:30 or 9:45 instead of round hours.

The International Date Line affects day of week.When it's Monday morning in the US, it's already Tuesday in Australia and New Zealand. The converter shows the correct day for each timezone.

Use city names for clarity."Eastern Time" could mean US Eastern or Australian Eastern. Use "New York" or "Sydney" to be specific. The converter uses IANA timezone names internally for accuracy.

Pro tip: For recurring meetings, check the conversion for both January and July. This reveals if DST changes will affect the meeting time in any location.

Common Questions

What's the best time for a global meeting?

For US-Europe-Asia, try 2-3 PM London time (9-10 AM New York, 10-11 PM Singapore). For US-Europe only, 3 PM London (10 AM New York, 4 PM Berlin) works well. No single time works for all regions.

How do I handle daylight saving time changes?

The converter automatically accounts for DST based on the date you select. If scheduling a recurring meeting, verify times for both summer and winter dates to catch any shifts.

Why does Sydney show a different day?

Sydney is 16-18 hours ahead of US timezones. When it's Monday morning in New York, it's already Tuesday morning in Sydney. The International Date Line causes this day difference.

Can I convert times for historical dates?

The converter uses current timezone rules. Historical DST rules have changed - some countries abolished it, others adopted it. For historical accuracy, use a dedicated historical timezone database.

What timezone should I use for UTC?

UTC (Coordinated Universal Time) is the global standard. It's also called GMT or Zulu time. Use UTC for timestamps in logs, databases, and APIs to avoid timezone confusion.

How accurate is the daylight saving calculation?

The converter uses the IANA timezone database which tracks DST rules worldwide. Rules can change with new legislation, but the database is updated regularly to reflect current laws.

What's the time difference between major cities?

London is 5 hours ahead of New York, 8 hours ahead of Los Angeles. Tokyo is 14 hours ahead of New York, 9 hours ahead of London. Sydney is 16 hours ahead of New York, 11 hours ahead of London.
