Questions

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

PST is currently 4 hours behind AST. Subtract 4 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 5 * * 1-5 in PST.

What is the time difference between AST and PST?

Atlantic Time is UTC-4 / UTC-3 and Pacific Time is UTC-8 / UTC-7. Right now pST is currently 4 hours behind AST.

Does daylight saving time affect AST to PST cron conversion?

AST and PST observe daylight saving time, so the difference between AST (UTC-4 / UTC-3) and PST (UTC-8 / UTC-7) changes during the year. Re-check your converted cron after each DST change.

What is midnight AST in PST cron?

Midnight in AST (0 0 * * *) is 0 20 * * * in PST, on the previous day.
