It is 03:03 on Friday, October 30, 2026 in London, United Kingdom. The city runs on UTC+0 (GMT), which puts it 3 hours ahead of Brasília.
Time zone and UTC offset in London
London follows the Europe/London time zone, abbreviated GMT. Right now its offset from Coordinated Universal Time is UTC+0.
Standard time is in effect at the moment, and London does observe daylight saving time. The next change comes on Sunday, March 28, 2027 at 01:00: clocks go forward 1 hour, so at 01:00 the clock jumps to 02:00 and the offset becomes UTC+1. From that day the difference from Brasília is 4 hours ahead. The change after that is on Sunday, October 31, 2027 at 02:00.
Time difference between Brasília and London
To convert, take Brasília time and add 3 hours; when the sum passes midnight, the date in London is already the next day. The table uses today's offsets.
Going the other way, local noon in London is 09:00 in Brasília, and local midnight is 21:00 (previous day) in Brasília. Because London is ahead, its calendar date is one day later than in Brasília from 21:00 until midnight Brasília time. Keep this in mind for deadlines, flights and anything scheduled around the start or end of a day.

Best time to call London from Brazil
Taking a 9:00 to 18:00 working day on both sides, the shared window runs from 09:00 to 15:00 in Brasília, which is 12:00 to 18:00 in London. That leaves 6 hours of overlap: enough for most meetings, but book early. Because London changes its clocks, this window shifts by one hour after the next change.
