Time zone differences with overseas clients: Beijing time chart
Short answer: Know the gap between Beijing time (UTC+8, no daylight saving) and each buyer’s city, including when their clocks change. Then use the hours you overlap, prepare complete replies so one exchange settles the question, set clear reply expectations, and cover key markets with a rota.
China runs on a single time zone, Beijing time (UTC+8), with no daylight saving. The gap to your buyers changes during the year only because many of their countries move their clocks. Once you know each gap and when it shifts, you can plan your day around the hours you overlap, and write replies that settle things in one exchange instead of three.
Beijing time vs major export markets
The table shows how far common markets are from Beijing. “Winter” and “summer” refer to the northern hemisphere.
| Market | UTC offset | Northern winter | Northern summer |
|---|---|---|---|
| US East (New York and others) | UTC−5, daylight saving UTC−4 | 13 hours behind Beijing | 12 hours behind |
| US West (Los Angeles and others) | UTC−8, daylight saving UTC−7 | 16 hours behind | 15 hours behind |
| United Kingdom | UTC+0, daylight saving UTC+1 | 8 hours behind | 7 hours behind |
| Germany, France, Spain, Italy | UTC+1, daylight saving UTC+2 | 7 hours behind | 6 hours behind |
| Moscow, Russia | UTC+3, no daylight saving | 5 hours behind | 5 hours behind |
| Saudi Arabia | UTC+3, no daylight saving | 5 hours behind | 5 hours behind |
| United Arab Emirates | UTC+4, no daylight saving | 4 hours behind | 4 hours behind |
| Israel | UTC+2, daylight saving UTC+3 | 6 hours behind | 5 hours behind |
| India | UTC+5:30, no daylight saving | 2.5 hours behind | 2.5 hours behind |
| São Paulo, Brazil | UTC−3, no daylight saving | 11 hours behind | 11 hours behind |
| Mexico City | UTC−6, no daylight saving since 2022 | 14 hours behind | 14 hours behind |
| Sydney, Australia | UTC+10, daylight saving UTC+11 (roughly October to April) | 3 hours ahead of Beijing | 2 hours ahead |
Sydney is in the southern hemisphere, so its daylight saving falls in the northern winter. That is why it is three hours ahead of Beijing from about October to April, and two hours ahead for the rest of the year.
Daylight saving: when the gap changes by an hour
In the United States, daylight saving starts on the second Sunday in March and ends on the first Sunday in November. In the EU and the UK, it starts on the last Sunday in March and ends on the last Sunday in October. Around these dates, the gap between your buyer and Beijing changes by one hour.
The weeks that cause the most mistakes are mid-to-late March and late October to early November, when the US has changed its clocks and Europe has not, or the other way round. A call that was at 22:00 Beijing time last week may now be at 21:00.
- Write both times when you propose a call, for example “Tuesday 9:00 New York time (21:00 Beijing time)” while the US is on daylight saving.
- Create calendar invites in the buyer’s time zone, so the calendar handles the change for you.
- For a recurring call, confirm the time again in the week the clocks change.
Find the hours you overlap with each market
Convert the buyer’s working hours into Beijing time and you will see when you are both online. The examples below use northern winter times. When Europe and the US are on daylight saving, the matching Beijing time is one hour earlier.
- Europe: 9:00 in Germany or France is 16:00 in Beijing, and 9:00 in the UK is 17:00. Your afternoon and evening are the main window.
- United States: 8:00 in New York is 21:00 in Beijing, and 16:00 in Los Angeles is 8:00 the next morning in Beijing. The overlap is small, so many teams handle US buyers in a fixed block in the Beijing evening or early morning.
- Middle East: 9:00 in Dubai is 13:00 in Beijing, and 9:00 in Riyadh is 14:00, so most of your afternoon overlaps. Working weeks differ in some countries: in Saudi Arabia, for example, the weekend is Friday and Saturday. Working hours may also be shorter during Ramadan, so go by what the buyer tells you.
- India and Australia: 10:00 in India is 12:30 in Beijing. Sydney is only two or three hours ahead, so most of your working day overlaps.
- Latin America: 9:00 in São Paulo is 20:00 in Beijing, and 9:00 in Mexico City is 23:00.
Prepare so one exchange settles the question
With a large time difference, every question and answer can cost a full day. Cutting the number of round trips is more practical than staying up to reply within seconds.
- Write complete messages. When you quote, include unit price, currency, Incoterm, MOQ, lead time, payment terms and validity, so the buyer doesn’t need to ask.
- Answer the next question too. After asking about price, buyers usually ask about samples and lead time, so add a line on both.
- Keep key files ready. Catalog, spec sheets, certificates, factory videos and packaging options should be one tap away.
- Offer options. Instead of “What do you think?”, ask “Option A or option B?”, so the buyer can reply as soon as they read it.
- Number the open points. List what you need confirmed as 1, 2, 3, so the buyer can answer point by point without missing one.
Set reply-time expectations with an away message
The WhatsApp Business app lets you set an away message that answers automatically outside your business hours, so buyers know when to expect you. This is a setting inside WhatsApp itself. Keep it short and state the time zone:
With important buyers, you can also set expectations early: “We usually reply during your morning. For anything urgent, please call.” Once expectations are clear, a buyer is far less likely to worry when a few hours pass without an answer.
Rotas, world clocks and when to press send
- Use a rota for key markets. If many of your buyers are in the US, colleagues can take turns covering the Beijing evening or early morning, so urgent inquiries and order issues are handled on time. Plan the rota ahead and hand over conversation notes at each change.
- Use world clocks. Add clocks for your main buyers’ cities to your phone and computer, and show two time zones in your calendar. Check them before you propose a call.
- Avoid messaging in the buyer’s night. A phone can buzz while they sleep. For anything that isn’t urgent, save your reply as a draft and send it yourself when their working day starts. If a buyer says any time is fine, follow their preference.
- Watch public holidays. Besides the time difference, keep track of the buyer’s public holidays, and tell buyers early about Chinese New Year and National Day closures on your side.
Frequently asked questions
How many hours is Beijing ahead of the US?
The US East Coast is 13 hours behind Beijing in winter and 12 hours behind during daylight saving. The West Coast is 16 hours behind in winter and 15 during daylight saving. US daylight saving runs from the second Sunday in March to the first Sunday in November.
When is the best time to contact European buyers from China?
A European morning is a Beijing afternoon, so from about 15:00 or 16:00 Beijing time into the evening works well. The exact window depends on the buyer’s working hours and on whether daylight saving is in effect.
Do I need to reply at once when a buyer messages in the middle of the night?
Usually not. Set an away message that states your hours, then send a complete reply when you start work. That is often better than a rushed answer at 2 a.m. Urgent order issues can follow your team’s on-call arrangement.
Do buyers in the Middle East work the same days as we do?
Not always. Weekends differ in some countries, and working hours may change during Ramadan. The safest approach is to ask the buyer about their working days and hours and note them in your customer records.
Does China use daylight saving time?
No. China has not used daylight saving since 1991, so Beijing time stays at UTC+8 all year. Any change in the gap to a buyer comes from clock changes on their side.
