Time Zone Difference Calculator
Calculate the number of hours separating two time zones by entering their offsets from Coordinated Universal Time (UTC). Perfect for scheduling international meetings or travel calls.
Check live world clock data for mission-critical events; this tool assumes static offsets and does not fetch live time zone updates.
Examples
- UTC−5 and UTC+2 ⇒ 7 hours difference
- UTC+1 and UTC+1 ⇒ 0 hours difference
- UTC+5.5 and UTC−3 ⇒ 8.5 hours difference
FAQ
Where can I find current UTC offsets?
Check world clock apps, airline schedules, or official time services for up-to-date offsets including daylight saving adjustments.
Does the calculator handle negative values automatically?
Yes. The formula uses the absolute difference, so the order of locations does not matter.
How do I account for daylight saving time?
Use the offset that applies on the target date; many regions publish separate standard and daylight offsets.
Can I get the result in minutes instead of hours?
Multiply the output by 60 to convert hours to minutes. For example, 2.5 hours equals 150 minutes.
What about regions with unusual offsets like UTC+5:45?
Enter the decimal equivalent (5.75) to include those quarter-hour differences in the calculation.
Additional Information
- Positive offsets are east of Greenwich (ahead of UTC); negative offsets are west (behind UTC).
- Many regions observe daylight saving time, shifting offsets by ±1 hour during certain months—verify current offsets before scheduling.
- Half-hour and quarter-hour offsets exist (e.g., India UTC+5.5, Nepal UTC+5.75); enter decimals to capture them accurately.
- To convert the hour difference into minutes, multiply the decimal portion by 60 (0.5 hours equals 30 minutes).
