Convert a date and time from one city or IANA time zone to another, compare live local times, and find overlapping working hours for meetings. This free tool runs in your browser, accounts for daylight saving time using your browser's time-zone data, and does not require an account.

Disclaimer

This Time Zone Converter is provided for general information, planning, and educational purposes only. Converted times are calculated in your browser from the date, time, and IANA time zones you select, using your browser's internationalization data. Results are not an official timetable, legal record, or guarantee of when an event occurs.

Daylight saving rules, political time-zone changes, and browser time-zone databases can differ. Always confirm important meetings, travel connections, broadcasts, and deadlines with the other party or an official source. Web4pps does not provide legal, travel, or scheduling advice.

How to Use Time Zone Converter

Follow these steps to convert a date and time between cities and time zones:

• Select the date — choose the calendar date in the source time zone.
• Select the time — enter the local time you want to convert.
• Choose the source time zone — search by city (for example Manila, London, or New York) or by IANA identifier such as Asia/Manila.
• Choose the destination time zone — pick the city or zone you want to convert into.
• Read the converted result — the matching date, time, UTC offset, and day difference (same day, one day earlier, or one day later) update immediately.
• Optional controls — swap the two zones, jump to today, move by a day or hour, switch 12-hour and 24-hour display, copy the result, or share a link to the same conversion.

Use the World Clock tab to watch current local times in several cities at once. Use the Meeting Planner tab to add participant time zones, set working hours and meeting duration, and highlight overlapping hours that work for everyone.

The converter interprets your entered time as wall-clock time in the source zone, finds the corresponding instant, then displays that instant in the destination zone. It does not add a fixed offset such as UTC−5 for every date, which would be wrong when daylight saving time applies.

Who should use Time Zone Converter

This free tool is for anyone who needs a clear, DST-aware conversion without creating an account or installing software.

• Remote teams scheduling calls across countries and continents.
• Overseas Filipino workers (OFWs), travelers, and families coordinating times between the Philippines and destinations such as the United States, the United Kingdom, the Middle East, or Australia.
• Students and professionals joining online classes, webinars, or interviews.
• Event planners comparing the same moment in several cities.
• Anyone learning how UTC, IANA time zones, and daylight saving time affect local clocks.

It is not a replacement for a calendar product, airline booking system, or official government time service. Use it as a planning aid, then confirm critical times with the people or organizations involved.

Frequently Asked Questions

What is a time zone converter?
A time zone converter takes a date and time in one location and shows the equivalent date and time in another location. This tool also shows the UTC offset for the selected moment, whether the result falls on a different calendar day, a live world clock, and a meeting overlap planner.

Does the converter account for daylight saving time?
Yes. Conversions use IANA time zones (for example America/New_York or Europe/London) and your browser's time-zone database, so the UTC offset is calculated for the exact date and time you enter rather than a year-round shortcut.

What is UTC?
UTC (Coordinated Universal Time) is the global time standard. Time zones are described as an offset from UTC, such as UTC+08:00 for the Philippines. UTC itself does not observe daylight saving time.

Why does the time difference change during the year?
Some regions move their clocks forward or back for daylight saving time. If one city observes DST and the other does not—or they change on different dates—the difference between them can shift by an hour. That is why this converter uses the selected date instead of a fixed offset.

How accurate is the converter?
Accuracy depends on the IANA time-zone data built into your browser. Keep your browser updated for the latest DST and political time-zone changes. For high-stakes scheduling, confirm the result with the other participants.

What time zone is Manila?
Manila uses the IANA zone Asia/Manila and is normally UTC+08:00. The Philippines does not currently observe daylight saving time.

Can I convert times between multiple cities?
Yes. Convert one source time to a destination on the Converter tab, add several cities on the World Clock tab, or compare working hours for a group on the Meeting Planner tab. You can compare up to 15 time zones at once.

Does the converter work on mobile?
Yes. The layout stacks date, time, source, swap, destination, and result for small screens, with large tap targets for the main controls.

Is this time zone converter free?
Yes. You can use it as often as you like at no cost, with no account required.

Are my conversion details stored?
Conversions run in your browser. See Privacy Information below for details.

Privacy Information

The Time Zone Converter runs entirely in your browser. The date, time, and time zones you enter are used only on your device to compute results. Web4pps does not require an account to use this tool, and conversion inputs are not sent to our servers for storage.

Optional preferences such as 12-hour or 24-hour display, recently used time zones, world clock cities, and meeting working hours are saved in your browser's local storage so they can be restored on your next visit. You can clear them by clearing site data in your browser. Shareable links contain only the time zones, date, and time needed to restore a conversion—not your name or other personal information. Do not put private details in the URL.
