AWS EventBridge support
AWS EventBridge implementation of cron does not use 0 based day of week, instead it is 1-7 SUN-SAT (instead of 0-6),
as well as supporting additional expression features such as first-weekday and last-day-of-month. Source
Because of that, cronrange does not support the full range of expression wildcards available on AWS EventBridge.
| Wildcard | Example expression | Supported |
|---|---|---|
L |
*/5 * L * ? * |
Yes |
W |
*/30 * 1W * ? * |
No |
# |
*/30 * ? * 3#2 * |
No |
? |
0 8 1 * ? * |
Yes |
Classic cron expression wildcards such as ,, /, - and * are supported.
