Questions

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

AST is currently 15 hours behind AEST. Subtract 15 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 AEST) becomes 0 18 * * 0-4 in AST.

What is the time difference between AEST and AST?

Australian Eastern Time is UTC+10 / UTC+11 and Atlantic Time is UTC-4 / UTC-3. Right now aST is currently 15 hours behind AEST.

Does daylight saving time affect AEST to AST cron conversion?

AEST and AST observe daylight saving time, so the difference between AEST (UTC+10 / UTC+11) and AST (UTC-4 / UTC-3) changes during the year. Re-check your converted cron after each DST change.

What is midnight AEST in AST cron?

Midnight in AEST (0 0 * * *) is 0 9 * * * in AST, on the previous day.
