China uses a single time zone, and this guide covers them all: the offset in each city, the daylight saving dates, the best time to call from New York or London, and how to convert any time. The 2 major cities covered here are Shanghai, Beijing.

Time zones in China
| City | IANA time zone | Offset in January 2026 | Offset in July 2026 | Daylight saving? |
|---|---|---|---|---|
| Shanghai | Asia/Shanghai | UTC+08:00 | UTC+08:00 | No |
| Beijing | Asia/Shanghai | UTC+08:00 | UTC+08:00 | No |
With one time zone, China is simple: the whole country is on Asia/Shanghai, UTC+08:00 from UTC all year. There is no internal time difference to worry about — a meeting scheduled for 10am in Shanghai is 10am everywhere in the country. The only question is the difference from the rest of the world, and the table above gives it for January and July.
Daylight saving in China
None of the cities covered here observes daylight saving — China stays on the same offset all year. Shanghai: China uses a single time zone for the whole country and last observed daylight saving in 1991. The experiment was dropped because a single national clock change caused confusion across a country spanning five geographical time zones. Beijing: China uses a single time zone for the whole country and last observed daylight saving in 1991. The experiment was dropped because a single national clock change caused confusion across a country spanning five geographical time zones. The advantage is simplicity: the offset you learn is the offset all year, and a meeting scheduled in January is at the same time in July.
What time is it in China when it is 12:00 UTC?
| City | Local time at 12:00 UTC (15 January 2026) |
|---|---|
| Shanghai | 8:00 pm |
| Beijing | 8:00 pm |
How to convert a time to China
Take 3pm in London. In January, London is UTC+00:00 and Shanghai is UTC+08:00, so 3pm in London is 11:00 pm in Shanghai. In July, London is UTC+01:00 and Shanghai is UTC+08:00, so 3pm in London is 10:00 pm in Shanghai. The answer is the same in July as in January, because neither place changes its offset — Shanghai does not observe daylight saving. The time zone converter does this for any two cities and any date, and the UTC converter converts from UTC.
The best time to call China
The overlap of a 9am–5pm working day between Shanghai and New York is none in January 2026; between Shanghai and London it is none. There is no overlap with either city in a normal working day, so a call has to be early morning or late evening for someone — the kindest time is usually early morning in the city further east.
The time in China through the year
The offset of Shanghai month by month in 2026 — the local time when it is 12:00 UTC on the 15th of each month:
| Month | UTC offset | Local time at 12:00 UTC |
|---|---|---|
| January | UTC+08:00 | 8:00 pm |
| February | UTC+08:00 | 8:00 pm |
| March | UTC+08:00 | 8:00 pm |
| April | UTC+08:00 | 8:00 pm |
| May | UTC+08:00 | 8:00 pm |
| June | UTC+08:00 | 8:00 pm |
| July | UTC+08:00 | 8:00 pm |
| August | UTC+08:00 | 8:00 pm |
| September | UTC+08:00 | 8:00 pm |
| October | UTC+08:00 | 8:00 pm |
| November | UTC+08:00 | 8:00 pm |
| December | UTC+08:00 | 8:00 pm |
Shanghai stays on the same offset all twelve months, because it does not observe daylight saving — the table is the same in January and in July, and there is no clock change to remember. The world clock for Shanghai shows the live time and the offset in effect today.
China and the rest of the world
The time difference from Shanghai to six major cities, in January and in July 2026:
| City | Difference in January | Difference in July |
|---|---|---|
| New York | 13 hours ahead | 12 hours ahead |
| London | 8 hours ahead | 7 hours ahead |
| Paris | 7 hours ahead | 6 hours ahead |
| Tokyo | 1 hour behind | 1 hour behind |
| Sydney | 3 hours behind | 2 hours behind |
| Dubai | 4 hours ahead | 4 hours ahead |
The differences change between January and July wherever one of the two cities observes daylight saving and the other does not — or wherever they change on different dates. The time zone converter gives the difference for any date, so a conversion done for January is not reused for July without checking.
Calling China from London
In January there is no overlap between the working hours of Shanghai and London, so any call has to be early morning or late evening for one side. The kindest time is usually early morning in the city further east — 8am there is late evening the previous day in the other city — or late evening in the city further west. The meeting planner shows the overlap for any set of cities.
