Frequently Asked Questions
How does the time zone converter work?
Select a source time zone and a target time zone, then enter a date and time. The tool uses your browser's built-in Intl.DateTimeFormat API to compute the exact converted time, accounting for UTC offsets and daylight saving time rules automatically.
Does the tool handle Daylight Saving Time (DST)?
Yes. The converter detects whether DST is in effect for each time zone on the selected date and applies the correct offset. A "DST" badge is shown next to the time zone when summer time is active, so you always know the current state.
Can I compare more than two time zones at once?
Yes. Use the "Add Timezone" button in the comparison section to add as many additional time zones as you need. Each entry shows the converted time, date, and UTC offset for the same input date and time.
What does the "Now" button do?
Clicking "Now" fills the date and time fields with the current UTC time and sets the source time zone to UTC, giving you an instant real-time conversion to any target time zone.
How do I search for a city or time zone?
Type any part of a city name, region, or time zone identifier (e.g., "Tokyo", "EST", "Pacific") in the search box above the dropdown. The list filters in real time to show matching options.
What is UTC offset?
A UTC offset (e.g., UTC+05:30) shows how many hours and minutes a time zone is ahead of or behind Coordinated Universal Time. The tool displays the current offset for both the source and target time zones based on the selected date.
Is my data sent to any server?
No. All conversions happen entirely in your browser using the JavaScript Intl API. No dates, times, or personal data are transmitted to any server.
Why do some time zones show half-hour or quarter-hour offsets?
Not all time zones are aligned on full hours. For example, India Standard Time is UTC+05:30 and Nepal Standard Time is UTC+05:45. The converter handles all fractional offsets correctly.
Can I swap the source and target time zones?
Yes. Click the "⇅ Swap" button between the two time zone selectors to instantly reverse the direction of the conversion.
What time zones are available?
The tool includes 43 popular time zones covering every major region and continent, from UTC and US time zones to Europe, Africa, Asia, Australia, and the Pacific. Search by city name or time zone abbreviation to find what you need quickly.
How accurate is the time difference shown?
The displayed time difference is calculated from the exact UTC offsets of both time zones on the selected date. It accounts for DST changes, so the result is accurate to the minute.
