Beijing time to UK time for every Superbuy deadline
Superbuy writes its deadlines in Beijing time, which never changes. The UK clock does, so the same promise lands at a different British hour depending on the date.
Beijing stays on UTC+8 while the UK moves twice a year
China uses one time zone, UTC+8, all year, with no daylight saving. The UK uses Greenwich Mean Time in winter and British Summer Time, one hour ahead, in summer. gov.uk sets out the rule: clocks go forward 1 hour at 1am on the last Sunday in March and back 1 hour at 2am on the last Sunday in October.
So the gap to Beijing is 7 hours from late March to late October and 8 hours the rest of the year. For 2026 the switch back is on 25 October; the next switch forward is on 28 March 2027. The legal basis is the Summer Time Order 2002.

Every Beijing time Superbuy publishes, converted
These are the Beijing times that appear in Superbuy’s service standards, with their UK equivalents in each half of the year. “Next day” is the Beijing next day, which starts at 17:00 BST or 16:00 GMT on the UK side.
Read the table as a daily rhythm. Beijing’s working day falls inside the British night and early morning, so most of what Superbuy does for you happens while you are asleep. By the time a UK office opens at nine, the Beijing afternoon is already half gone in summer and more than half gone in winter. A message sent at lunchtime in London lands after the desk has closed.

When to submit an order from the UK
Help 162 gives two processing windows. An order submitted between 09:00 and 18:00 Beijing is processed within 6 hours. One submitted between 18:00 and 09:00 is processed by 14:00 “the next day”.
For a UK shopper that splits the day oddly. In GMT, anything you submit from 10:00 in the morning until 01:00 the following night falls in the overnight window. The 6-hour window is the small hours: 01:00 to 10:00 GMT, or 02:00 to 11:00 BST. An order sent before work in the morning gets the fast lane; an evening order waits for the Beijing afternoon.
“The next day” is itself unclear for orders submitted after midnight in Beijing. An order at 02:00 Beijing on Tuesday is already on Tuesday; whether “14:00 the next day” means Tuesday or Wednesday is not stated. Help 1441 uses the same windows but measures from payment rather than submission. Read with help centre article 162 and help centre article 1441.
The week the clocks go back
Any service whose window crosses 01:00 UTC on Sunday 25 October 2026 ends an hour earlier on a British clock than a simple “add 24 hours” suggests. A 24-hour service bought at 20:00 BST on Saturday is due at 19:00 GMT on Sunday. A 48-hour return response requested at 09:00 BST on Saturday is due at 08:00 GMT on Monday.
The hour between 01:00 and 02:00 happens twice that night in the UK. If you placed an order at 01:30 on 25 October your device may show either. The calculator requires you to choose BST for the first occurrence or GMT for the second; it does not silently choose for you.
28 March 2027: the hour that never happens
On the last Sunday in March the UK clocks jump from 01:00 to 02:00 GMT. A deadline that crosses that moment ends an hour later on a British clock: a 24-hour service bought at 20:00 GMT on Saturday 27 March 2027 is due at 21:00 BST on Sunday.
The UK times between 01:00 and 01:59 that night do not exist. The calculator rejects those nonexistent local times and asks you to check the actual timestamp.
Dates, weekdays and the Beijing calendar
Payout days and holidays are counted on the Beijing calendar. A deadline that passes at 18:00 BST on a Sunday has passed at 01:00 on Monday in Beijing, so for payout purposes it was missed on a Monday, so the current weekly rule schedules an eligible credit for Tuesday of the following Beijing week, with holiday postponement where applicable.
The same applies to holidays. A service window that covers a UK Sunday evening already overlaps the Beijing Monday. Whenever a date matters, convert the time first and then read the weekday.
