Questions

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

WET is currently 4 hours ahead of AST. Add 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 13 * * 1-5 in WET.

What is the time difference between AST and WET?

Atlantic Time is UTC-4 / UTC-3 and Western European Time is UTC+0 / UTC+1. Right now wET is currently 4 hours ahead of AST.

Does daylight saving time affect AST to WET cron conversion?

AST and WET observe daylight saving time, so the difference between AST (UTC-4 / UTC-3) and WET (UTC+0 / UTC+1) changes during the year. Re-check your converted cron after each DST change.

What is midnight AST in WET cron?

Midnight in AST (0 0 * * *) is 0 4 * * * in WET.
