Questions

How do I convert a cron expression from AST to AEST?

AEST is currently 14 hours ahead of AST. Add 14 hours to the hour field, and shift the day-of-week if the time crosses midnight. For example, 0 9 * * 1-5 (weekdays at 09:00 AST) becomes 0 23 * * 1-5 in AEST.

What is the time difference between AST and AEST?

Atlantic Time is UTC-4 / UTC-3 and Brisbane Time (Queensland) is UTC+10. Right now aEST is currently 14 hours ahead of AST.

Does daylight saving time affect AST to AEST cron conversion?

AST observes daylight saving time, so the difference between AST (UTC-4 / UTC-3) and AEST (UTC+10) changes during the year. Re-check your converted cron after each DST change.

What is midnight AST in AEST cron?

Midnight in AST (0 0 * * *) is 0 14 * * * in AEST.
