Questions

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

EAT is currently 7 hours ahead of AST. Add 7 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 16 * * 1-5 in EAT.

What is the time difference between AST and EAT?

Atlantic Time is UTC-4 / UTC-3 and East Africa Time is UTC+3. Right now eAT is currently 7 hours ahead of AST.

Does daylight saving time affect AST to EAT cron conversion?

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

What is midnight AST in EAT cron?

Midnight in AST (0 0 * * *) is 0 7 * * * in EAT.
