Timezone Converter
Convert a time from one timezone to another, to coordinate across the world. No signup. Ideal for scheduling meetings, calls and events across different time zones.
This timezone converter converts a time from one timezone to another, directly in your browser. Enter a time and its zone, and see the equivalent time in another zone. No account, no install, so you can coordinate meetings, calls and events across the world on any device in seconds.
How to Convert a Time Between Zones Step by Step
- Enter the time. Type the time you want to convert into the input, the time as it is in the starting timezone.
- Choose the source timezone. Select the timezone the time is in, the zone from which you are converting.
- Choose the target timezone. Select the timezone you want to convert to, the zone in which you want to know the equivalent time.
- Convert the time. The tool works out the equivalent time in the target timezone, accounting for the difference between the two zones.
- Use the converted time. Use the equivalent time to coordinate across the zones, such as scheduling a meeting or knowing when an event occurs for you.
What Time Zones Are and Why They Exist
Time zones divide the world into regions that keep different local times, so that clocks roughly align with the sun across the globe. As you move around the world, the local time shifts, which is why a time in one place corresponds to a different time in another. A timezone converter works out the equivalent time between zones, essential for coordinating across the different local times of the world.
Time zones exist because the earth rotates, so the sun is overhead at different moments in different places. To keep local noon roughly at midday everywhere, regions set their clocks to different times, offset from a common reference. This means an event at a given time in one zone happens at a different local time in another, by the difference between their offsets, which is what a timezone conversion accounts for.
Timezone conversion is more than simple time arithmetic because of complications like the varying offsets between zones and, in many places, daylight saving time, which shifts clocks seasonally. These make working out the equivalent time by hand error prone, since you must know the correct offsets and whether daylight saving applies. A timezone converter handles these complications, giving the correct equivalent time reliably.
Timezone converters are essential for our connected world, where people coordinate across countries and continents. Scheduling a meeting, call, or event that involves people in different zones requires knowing the equivalent times, so everyone knows when it happens for them. Travellers, remote workers, and anyone dealing with people or events elsewhere use timezone conversion constantly. A converter makes coordinating across the world's time zones accurate and easy.

Frequently Asked Questions
How do I convert a time between timezones?
Enter the time you want to convert, select the timezone it is in, and select the timezone you want to convert to, and the tool works out the equivalent time in the target zone, accounting for the difference between the two zones. Use the equivalent time to coordinate across the zones, such as scheduling a meeting or knowing when an event occurs for you. The converter handles the offsets between zones and, where applicable, daylight saving time, giving the correct equivalent time reliably, which is essential for coordinating across the world's different local times.
What are time zones and why do they exist?
Time zones divide the world into regions that keep different local times, so that clocks roughly align with the sun across the globe. They exist because the earth rotates, so the sun is overhead at different moments in different places. To keep local noon roughly at midday everywhere, regions set their clocks to different times, offset from a common reference. This means a given moment corresponds to a different local time in different zones, by the difference between their offsets. A timezone converter works out these equivalent times, essential for coordinating across the world's different local times.
Why is timezone conversion more than simple time maths?
Because of complications like the varying offsets between zones and, in many places, daylight saving time, which shifts clocks seasonally. To convert correctly, you must know the right offset between the two zones and whether daylight saving applies at that time of year, which changes the offset. These factors make working out the equivalent time by hand error prone, since it is easy to use a wrong offset or forget daylight saving. A timezone converter handles these complications, applying the correct offsets and daylight saving adjustments, so it gives the correct equivalent time reliably rather than a simple but potentially wrong calculation.
How does daylight saving affect timezone conversion?
Daylight saving time, observed in many places, shifts clocks seasonally, typically forward in summer and back in winter. This changes the offset between zones at certain times of year, since a zone observing daylight saving is offset differently during the period it applies. So converting a time between zones must account for whether daylight saving is in effect in either zone at that time, as it affects the equivalent time. Forgetting daylight saving is a common cause of timezone conversion errors. A converter accounts for it, applying the correct offset including any daylight saving adjustment, for an accurate equivalent time.
How do I schedule a meeting across time zones?
To schedule a meeting across time zones, decide on a time, then use the converter to work out the equivalent time in each participant's timezone, and confirm it with each of them so everyone knows when the meeting happens for them. Converting the time for each zone ensures no one is confused about the timing. When sharing the time, state which timezone you mean, or give each person their local time, to avoid ambiguity. For important meetings, double check the converted times, since a timezone error could cause someone to miss or misschedule the meeting, so accurate conversion and clear communication are essential.
Why should I state the timezone when sharing a time?
Because without stating the timezone, people may assume a different zone than you mean, leading to confusion about when something actually happens. A time like a meeting start is only unambiguous if the timezone is clear, since the same clock time is a different moment in different zones. So when telling people a time across zones, you should state which timezone you mean, or better, give each person the time in their own local zone. This ensures everyone understands exactly when the meeting or event occurs, avoiding the confusion and missed connections that come from an unspecified timezone.
Who needs a timezone converter?
Timezone converters are essential for our connected world, where people coordinate across countries and continents. Remote workers and teams use them to schedule meetings and calls that suit colleagues in different zones. People arranging international meetings convert times so participants in each zone know when to join. Travellers convert times to understand schedules and coordinate with people elsewhere. Anyone joining an online event in another zone, or dealing with people or events in different time zones, uses timezone conversion. A converter makes coordinating across the world's time zones accurate and easy for all these needs.
Is the timezone converter free?
Yes, it is completely free with no account and no usage limit. You can convert as many times between time zones as you like, as often as you like, at no cost. It runs in your browser on any device, so there is nothing to download or install, and the equivalent time in the target zone appears instantly whenever you enter a time and choose the zones, helping you coordinate meetings, calls and events across the world's different time zones accurately.
