Time Zone Converter

What this converter actually uses as the starting time

The date-and-time field is interpreted in the local time zone configured on your device. The page then shows the corresponding time and date in Sydney, Tokyo, Dubai, London, New York and Los Angeles. This is especially useful when the converted location is already on the previous or next calendar day.

How to use the page

1. Confirm that your computer or phone is set to the correct local time zone.
2. Enter the local date and time you want to compare.
3. Select Convert Times.
4. Read both the clock time and the converted calendar date for each city.

Practical examples

Use the converter before scheduling an international video call, webinar, livestream, support window or family call. If an Australian meeting is proposed for 9:00 am, the result can show whether colleagues in London or New York would receive the invitation on the same calendar date and whether the time is practical.

Daylight saving and changing offsets

Time-zone offsets are not fixed all year. Cities such as Sydney, London and New York can change offset because of daylight saving, and those changes happen on different dates. The browser applies its time-zone rules to the date you enter, which is more reliable than assuming a permanent number of hours between cities.

Limitations

The listed cities are fixed on this page, and the source is your device's local zone rather than a separately selectable source zone. Government daylight-saving rules can also change over time. For travel, legal cut-offs, market opening times or other high-stakes timing, confirm the official local time and time zone from the relevant organisation.
