I have a cron job that is running twice an hour. It runs once at HH:00 and once at HH:45. This is strange because I tried to specify that it should run every 45 minutes as follows:
*/45 * * * * python my_job.py
This works fine for other jobs I run every 5 minutes as well as jobs that run every 20 minutes. However, I wonder if the fact that an hour isn't evenly divisible by 45 minutes is causing strange behavior. Why would my cron job be running twice an hour with this setup?
