🌍 Time Zones Converter
Plan meetings across the globe by translating date and time between time zones.
Select the origin and destination zones, choose a time, and copy the converted result with daylight-saving aware offsets.

Quick Reference
How to Use This Calculator
Select the source time zone
Choose where the original meeting or event occurs. Offsets cover UTC−12 through UTC+14.
Enter the local date and time
Use the date-time picker to capture the precise minute. The converter assumes the input is in the source time zone.
Pick the destination time zone
The converter displays the translated time and popular references (UTC, GMT, etc.) to share with participants.
Formula
UTC Timestamp = Local Time − (Source Offset × 3600 seconds)
Destination Time = UTC Timestamp + (Target Offset × 3600 seconds)
Offsets are based on static UTC differences. Adjust manually if daylight saving rules differ from the listed offset.
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Coordinating across time zones is tricky, especially when teams work on different continents. This converter takes a single date and time in one zone and translates it to another using UTC offsets up to ±14 hours.
The tool focuses on static offsets for clarity. Some regions observe daylight saving time (DST). If the offset for your target city changes seasonally, ensure you pick the correct offset for your scheduled date.
The quick reference section adds context by showing the converted time alongside UTC, GMT, and other popular offsets so you can paste the information directly into invites or documentation.
Frequently Asked Questions
Does this handle daylight saving time automatically?
The tool uses fixed UTC offsets. Check the correct offset for your date before converting if the region observes DST.
Can I add custom time zones?
Yes. Extend the TIMEZONE_LIST array in the source code with additional offsets or labels specific to your organization.
What if I need seconds or milliseconds?
Use the text field to include seconds manually (e.g., add :30). For sub-minute precision, adjust the output in your calendar tool after conversion.
How accurate is the conversion?
Within the listed offsets the conversion is exact. Just ensure you select the correct offset for the date when daylight saving rules apply.
