Convert Jenkins cron to Apache Airflow
Jenkins expressions look similar to Apache Airflow, but the differences matter. Paste yours below; the result is checked against the original run times.
What changes from Jenkins to Apache Airflow
- Jenkins
Hvalues pick a per-job offset, which no other system has. The converter replaces them with the start of the range.
Worked examples
| Schedule | Jenkins | Apache Airflow |
|---|---|---|
| every minute | * * * * * | * * * * * |
| every weekday at 8:30 AM | 30 8 * * 1-5 | 30 8 * * 1-5 |
Conversions that come with a warning
- every 5 minutes:
H/5 * * * *→*/5 * * * *. Jenkins H values have no equivalent elsewhere; they were replaced by their range start. - every 10 minutes:
H/10 * * * *→*/10 * * * *. Jenkins H values have no equivalent elsewhere; they were replaced by their range start. - every 15 minutes:
H/15 * * * *→*/15 * * * *. Jenkins H values have no equivalent elsewhere; they were replaced by their range start. - every 30 minutes:
H/30 * * * *→*/30 * * * *. Jenkins H values have no equivalent elsewhere; they were replaced by their range start.
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).
Jenkins uses the controller's time zone. Put TZ=Asia/Kolkata on its own first line of the trigger to override it.
minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, 0 and 7 = Sunday).
Airflow defaults to UTC. On a time-zone-aware DAG a cron schedule follows wall-clock time, so a daily 00:00 US/Eastern run moves between 04:00 and 05:00 UTC across daylight saving changes.

Frequently asked questions
How do I convert a Jenkins cron expression to Apache Airflow?
Paste it into the converter above with Jenkins as the source and Apache Airflow as the target. For example, * * * * * becomes * * * * *.
Is every Jenkins expression convertible to Apache Airflow?
Yes for the common schedules we tested (27 of 27), though unusual expressions with special characters might need manual review.
Does Apache Airflow run in the same time zone as Jenkins?
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.
