Cron Every Odd Day

To run a cron job every odd day, use the following cron string:

* * 1-31/2 * *

Let's break down this cron string:

Position 1: * means every minute
Position 2: * means every hour
Position 3: 1-31/2 means every 2 days of the month between 1 and 31
Position 4: * means every month
Position 5: * means every day of the week
