Convert UTC to Sydney time: when it is 12:00 UTC it is 23:00 in Sydney in January and 22:00 in July. Sydney is on UTC+10:00 in standard time and UTC+11:00 in daylight saving time. The full 24-hour conversion table is below, and the UTC converter does the conversion live for any date and time.
Try the tool: UTC Converter — convert any UTC time to Sydney time, or Sydney time back to UTC, with the offset shown.
Current UTC time and the time in Sydney
UTC is the world's reference time — it never observes daylight saving, and every other time zone is defined as an offset from it. The table shows four reference instants and what time they are in Sydney, in January and in July.
| UTC | Sydney in January | Sydney in July |
|---|---|---|
| 00:00 | 11:00 | 10:00 |
| 06:00 | 17:00 | 16:00 |
| 12:00 | 23:00 | 22:00 |
| 18:00 | 05:00 | 04:00 |
If the January and July columns are the same, Sydney's offset does not change — it does not observe daylight saving. If they differ by an hour, that hour is daylight saving, and the Sydney DST 2026 page gives the exact dates. The world clock shows the current time in Sydney live, and the time in Sydney page explains the city's time zone in full.
Sydney's offset from UTC
Sydney is on UTC+10:00 in winter and UTC+11:00 in summer, when daylight saving is in effect.
| Period | Offset | In effect |
|---|---|---|
| Standard time | UTC+10:00 | Late autumn to early spring |
| Daylight saving time | UTC+11:00 | Until 5 April 2026, then from 4 October 2026 in 2026 |
| Right now (11 November 2026) | UTC+11:00 | Daylight saving is in effect |
The offset is the only number you need. To convert UTC to Sydney time, add the offset. To convert Sydney time to UTC, subtract it. The offset to use is the one in effect on the date you are converting — not today's offset, and not the offset you remember from last summer. The converter on this page's tool does that for you: enter the UTC time and the date, and it looks up the offset from the IANA database for that date.
UTC to Sydney — full conversion table
Every hour of the day, converted from UTC to Sydney local time. The January column uses the winter offset (UTC+11:00); the July column uses the summer offset (UTC+10:00). Where the columns differ by an hour, that is daylight saving.
| UTC | Sydney (January) | Sydney (July) |
|---|---|---|
| 00:00 | 11:00 | 10:00 |
| 01:00 | 12:00 | 11:00 |
| 02:00 | 13:00 | 12:00 |
| 03:00 | 14:00 | 13:00 |
| 04:00 | 15:00 | 14:00 |
| 05:00 | 16:00 | 15:00 |
| 06:00 | 17:00 | 16:00 |
| 07:00 | 18:00 | 17:00 |
| 08:00 | 19:00 | 18:00 |
| 09:00 | 20:00 | 19:00 |
| 10:00 | 21:00 | 20:00 |
| 11:00 | 22:00 | 21:00 |
| 12:00 | 23:00 | 22:00 |
| 13:00 | 00:00 | 23:00 |
| 14:00 | 01:00 | 00:00 |
| 15:00 | 02:00 | 01:00 |
| 16:00 | 03:00 | 02:00 |
| 17:00 | 04:00 | 03:00 |
| 18:00 | 05:00 | 04:00 |
| 19:00 | 06:00 | 05:00 |
| 20:00 | 07:00 | 06:00 |
| 21:00 | 08:00 | 07:00 |
| 22:00 | 09:00 | 08:00 |
| 23:00 | 10:00 | 09:00 |
Use the table by finding the UTC hour in the first column and reading across. Note the date change: a UTC time late in the evening is the next day in Sydney when the offset is positive and large — 22:00 UTC is 09:00 the next day in Sydney in January — and a UTC time early in the morning is the previous day in Sydney when the offset is negative. The date matters as much as the time: a meeting at 02:00 UTC on Tuesday is a Monday evening meeting in the Americas.
When the offset changes
The offset changes twice a year. In 2026 the clocks go back on Sunday, 5 April 2026 and forward again on Sunday, 4 October 2026; in 2027 the clocks go back on Sunday, 4 April 2027 and forward again on Sunday, 3 October 2027. The offset moves from UTC+10:00 to UTC+11:00 and back again. On the change days themselves, the hour from 02:00 to 03:00 does not exist in spring and happens twice in autumn, so do not schedule anything for 02:30 on those dates.
Sydney time to UTC
The reverse conversion — Sydney local time back to UTC — is the same table read backwards. Six examples, for January:
| Sydney local | UTC (January) | UTC (July) |
|---|---|---|
| 00:00 | 13:00 | 14:00 |
| 06:00 | 19:00 | 20:00 |
| 09:00 | 22:00 | 23:00 |
| 12:00 | 01:00 | 02:00 |
| 15:00 | 04:00 | 05:00 |
| 21:00 | 10:00 | 11:00 |
The reverse table is the one to use when you are telling someone in another time zone when something happens in Sydney. A flight that departs Sydney at 09:00 local time departs at 22:00 UTC in January — and that UTC time is what the airline's systems, the air traffic controllers and the arrival airport all use. The flight time calculator works out the arrival time as well, including the date change.
Scheduling with UTC-based teams
Teams that work in UTC — software teams, aviation, shipping, scientific collaborations — schedule in UTC precisely because it never changes. If your team works in UTC, the time in Sydney is UTC plus UTC+11:00 in January and UTC plus UTC+10:00 in July, and the only question is which of those applies on the meeting date. Put the UTC time in the invitation as well as the local time, and nobody has to convert.
The practical working hours for a UTC-based team and Sydney are: 09:00–17:00 in Sydney is 22:00–06:00 UTC in January and 23:00–07:00 UTC in July. A meeting at 14:00 UTC is 01:00 in Sydney in January — inside the working day — and 00:00 in July. A meeting at 08:00 UTC is 19:00 in Sydney in January, which is before the working day starts. The meeting planner finds the overlap for any two cities, and the meeting time finder finds it for a whole team.
