❓ Frequently Asked Questions
How do I convert UTC to AEDT?
Add 11 hours to any UTC time. If the result is 24 or more, subtract 24 to get the time on the next calendar day. UTC 03:00 + 11 = AEDT 14:00. UTC 14:00 + 11 = 25 = 01:00 next day.
When is AEDT observed?
AEDT (UTC+11) is observed in NSW, Victoria, ACT, and Tasmania from the first Sunday in October to the first Sunday in April — Australia's summer. Outside this period, these states use AEST (UTC+10). Queensland stays on AEST year-round.
What is UTC midnight in AEDT?
UTC 00:00 = AEDT 11:00 AM. Add 11 hours: 0 + 11 = 11 AM. UTC midnight is late morning in Sydney.
For global meetings bridging UTC and AEDT (Sydney), UTC 22:00–23:00 works as AEDT 9:00–10:00 AM. Alternatively, UTC 02:00–04:00 = AEDT 1:00–3:00 PM is Australian afternoon.
What IANA timezone should I use for Sydney in code?
Use Australia/Sydney for Sydney/NSW and Australia/Melbourne for Melbourne. Both automatically switch between AEST (UTC+10) and AEDT (UTC+11). Do not hardcode +11 — use IANA names so DST transitions are handled automatically.
