AWS Region Time Converter

Convert a time between your local timezone and the typical timezone of an AWS region, for coordinating deployments or support windows.

Pick an AWS region and a time - this tool shows the equivalent local time in that region's typical timezone.

AWS resources themselves operate on UTC internally (e.g. CloudWatch timestamps) - this tool is about converting a wall-clock time for human coordination, not about how AWS stores timestamps.

Why Does This Matter?

When coordinating a maintenance window, deployment, or support call across a team or with users in a specific AWS region's geography, it helps to know what time it actually is there - even though AWS itself operates on UTC internally.

How to Use It

Select an AWS region.
Enter a date and time in your own local timezone.
See the equivalent time in that region's typical local timezone.

Limitations

Some AWS regions (like the US) span multiple time zones - this tool uses each region's most representative/primary time zone rather than modeling every possible local time zone within a large region.

Example

A team in India plans a database maintenance window for customers of an application in eu-west-2 (London). 02:00 London time is 06:30 or 07:30 in India, depending on whether the UK is on summer time (BST) or winter time (GMT). The converter handles those daylight saving changes for the date you choose.

Representative Time Zones for Popular Regions

Region	Location	Time zone
`us-east-1`	N. Virginia	America/New_York
`us-west-2`	Oregon	America/Los_Angeles
`eu-west-1`	Ireland	Europe/Dublin
`eu-central-1`	Frankfurt	Europe/Berlin
`ap-south-1`	Mumbai	Asia/Kolkata
`ap-southeast-1`	Singapore	Asia/Singapore

Remember: AWS Runs on UTC

CloudWatch timestamps, EventBridge rules and most AWS logs use UTC, whatever the region. Plan in local time for people, then convert to UTC for schedules - see our guide to AWS EventBridge cron expressions.

Build schedules with the AWS Cron Expression Helper, and look up region codes with the AWS Region Lookup.

Frequently Asked Questions

AWS services themselves use UTC. The tool shows the typical local time zone of the region's location, which is useful for planning maintenance windows for local users.

Using UTC everywhere avoids confusion with daylight saving time and multiple time zones. Convert to local time only for display.

Yes. Conversions use your browser's time zone data, which includes daylight saving rules for each location.
