GMT to AEST

Weekend mornings in Britain are the reliable family slot. At 9:00 AM in London it is evening in Sydney all year, between 6:00 and 8:00 PM, after dinner but before bed. Evening calls from the UK do not work: 7:00 PM in London is 6:00 AM the next morning in Sydney in January and 4:00 AM in July. On Christmas morning, a 9:00 AM call from London reaches Sydney at 8:00 PM, when the Australian side has already had lunch on the beach.

The gap shifts four times a year. It drops from 11 to 10 hours when the UK moves to BST on the last Sunday of March, to 9 hours when Sydney leaves daylight time on the first Sunday of April, back to 10 hours when Sydney restarts it on the first Sunday of October, and to 11 hours when the UK returns to GMT on the last Sunday of October.

A 3:00 PM Saturday kickoff in England is 2:00 AM Sunday in Sydney in January and midnight in August. Australians follow the Premier League at those hours, and the 12:30 PM Saturday game, at 11:30 PM in Sydney in January, is the friendliest slot. Australia's own A-League runs through the Australian summer, so a 7:45 PM match in Sydney is 8:45 AM in London.

Trade between the two countries has grown since the UK–Australia free trade agreement took effect in May 2023, and London–Sydney teams typically meet first thing in the London morning, which is the end of the Sydney day. Compare other cities on the time zone converter.
