[SOLVED] AWS cron expression to run every month, every 3 months and once a year

Issue

I'm trying to create CRON expressions in YAML:

1. AWS Cron expression to run at 6AM every month: This what I have: cron(0 6 1 * ? *)
2. Run every 3 months
3. Run once a year in January

Can someone please help with this. Appreciate it greatly

Solution

Try:

2. cron(0 0 1 */3 * *)
3. cron(0 0 1 1 * *)
