Questions

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

AST is currently 5 hours ahead of AKST. Add 5 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 AKST) becomes 0 14 * * 1-5 in AST.

What is the time difference between AKST and AST?

Alaska Time is UTC-9 / UTC-8 and Atlantic Time is UTC-4 / UTC-3. Right now aST is currently 5 hours ahead of AKST.

Does daylight saving time affect AKST to AST cron conversion?

AKST and AST observe daylight saving time, so the difference between AKST (UTC-9 / UTC-8) and AST (UTC-4 / UTC-3) changes during the year. Re-check your converted cron after each DST change.

What is midnight AKST in AST cron?

Midnight in AKST (0 0 * * *) is 0 5 * * * in AST.
