Time Difference Between Beijing and London

Seven hours leaves Beijing and London one shared slice of day, and only one. London's morning is Beijing's late afternoon: 9 AM to noon in London is 4 PM to 7 PM in Beijing. That is the entire window. By 2 PM in London the Beijing office has left, and Beijing's own morning happens while London sleeps. The Beijing side gives up the tail of its day as a matter of course, since a 6 PM meeting there is 11 AM in London and easy for anyone to attend. London teams wanting more room should start at 8 AM, which reaches Beijing at 3 PM instead of 4 PM. It is the rare adjustment that costs the person making it and helps the other side.

Beijing's clock is constant, so all the movement on this pair comes from London's daylight saving. The gap is eight hours from January 1 to March 28, seven hours from March 29 to October 24, and eight again from October 25 through December 31. Winter costs the Beijing side an hour of evening, because the 4 PM slot that matches London's 9 AM in summer becomes 5 PM once the clocks go back. The other date worth putting in the calendar is Chinese New Year, which moves every year and closes offices for a week or more around it. A London team setting a February deadline against a Beijing counterpart should look up the actual date rather than assume the month is ordinary.

Roughly ten to eleven hours nonstop, though the figure depends on the carrier: Chinese airlines still fly the short northern track over Russia, while European ones routing around that airspace take longer where they operate the route at all. Westbound to London is the kinder arrival, a long day that finishes at a plausible hour. Eastbound to Beijing lands you in late afternoon or evening with a body seven or eight hours behind local time, and the first night is usually broken around 2 AM. Leave a day before anything that matters. Morning daylight after an eastbound arrival does more for the adjustment than anything sold at the airport pharmacy.
