Questions

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

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

What is the time difference between AST and WAT?

Atlantic Time is UTC-4 / UTC-3 and West Africa Time is UTC+1. Right now wAT is currently 5 hours ahead of AST.

Does daylight saving time affect AST to WAT cron conversion?

AST observes daylight saving time, so the difference between AST (UTC-4 / UTC-3) and WAT (UTC+1) changes during the year. Re-check your converted cron after each DST change.

What is midnight AST in WAT cron?

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