Questions

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

PHT is currently 12 hours ahead of AST. Add 12 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 21 * * 1-5 in PHT.

What is the time difference between AST and PHT?

Atlantic Time is UTC-4 / UTC-3 and Philippine Time is UTC+8. Right now pHT is currently 12 hours ahead of AST.

Does daylight saving time affect AST to PHT cron conversion?

AST observes daylight saving time, so the difference between AST (UTC-4 / UTC-3) and PHT (UTC+8) changes during the year. Re-check your converted cron after each DST change.

What is midnight AST in PHT cron?

Midnight in AST (0 0 * * *) is 0 12 * * * in PHT.
