It is 10:05 on Saturday, October 3, 2026 in Adelaide, Australia. The city runs on UTC+9:30 (ACST), which puts it 12 hours 30 minutes ahead of Brasília.
Time zone and UTC offset in Adelaide
Adelaide follows the Australia/Adelaide time zone, abbreviated ACST. Right now its offset from Coordinated Universal Time is UTC+9:30. Note the 30-minute fraction: unlike most of the world, this zone is not set on a whole hour, so the difference from Brasília is not a round number of hours either.
Standard time is in effect at the moment, and Adelaide does observe daylight saving time. The next change comes on Sunday, October 4, 2026 at 02:00: clocks go forward 1 hour, so at 02:00 the clock jumps to 03:00 and the offset becomes UTC+10:30. From that day the difference from Brasília is 13 hours 30 minutes ahead. The change after that is on Sunday, April 4, 2027 at 03:00.
Time difference between Brasília and Adelaide
To convert, take Brasília time and add 12 hours 30 minutes; when the sum passes midnight, the date in Adelaide is already the next day. The table uses today's offsets.
Going the other way, local noon in Adelaide is 23:30 (previous day) in Brasília, and local midnight is 11:30 (previous day) in Brasília. Because Adelaide is ahead, its calendar date is one day later than in Brasília from 11:30 until midnight Brasília time. Keep this in mind for deadlines, flights and anything scheduled around the start or end of a day.
