Field layout and time zones
minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, 0 and 7 = Sunday).
Set spec.timeZone (Kubernetes 1.27+) to a name like Asia/Kolkata. Without it the schedule follows the controller's time zone, usually UTC.
minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-6, 0 = Sunday).
GitHub Actions schedules are always UTC. Convert your local time to UTC before writing the expression.
Go the other way

Frequently asked questions
How do I convert a Kubernetes cron expression to GitHub Actions?
Paste it into the converter above with Kubernetes as the source and GitHub Actions as the target. For example, * * * * * becomes * * * * *.
Is every Kubernetes expression convertible to GitHub Actions?
Yes for the common schedules we tested (27 of 27), though unusual expressions with special characters might need manual review.
Does GitHub Actions run in the same time zone as Kubernetes?
Not necessarily. Conversion changes the syntax, not the time zone. Check where each system evaluates the schedule before you rely on the same clock times.
