Questions

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

AST is currently 1 hour ahead of EST. Add 1 hour 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 EST) becomes 0 10 * * 1-5 in AST.

What is the time difference between EST and AST?

Eastern Time is UTC-5 / UTC-4 and Atlantic Time is UTC-4 / UTC-3. Right now aST is currently 1 hour ahead of EST.

Does daylight saving time affect EST to AST cron conversion?

EST and AST observe daylight saving time, so the difference between EST (UTC-5 / UTC-4) and AST (UTC-4 / UTC-3) changes during the year. Re-check your converted cron after each DST change.

What is midnight EST in AST cron?

Midnight in EST (0 0 * * *) is 0 1 * * * in AST.
