Cron syntax for bi-weekly server task

Does anyone know what the correct syntax for a cron scheduled task would be if I were to run a task every 2 weeks (e.g. On the first and 15th of every month).

Tried this - 0 0 7 ? * 1F,15W

Of course that didnt work so Im stuck here. Any guide out there that shows use cases?

Re: Cron syntax for bi-weekly server task

Hi JTorrico,

Would something like this help?
   0 7 1-7,15-21 * 1
... would run on the 1st and 3rd Monday of a month.

or maybe
   0 08 1-7,15-21 * 3
... would run on the 1st and 3rd Wednesday of every month.

For a Saturday run the last digit would change to 6.
example: 0 08 1-7,15-21 * 6

Have a look at this URL it offers some good detail that you may find helpful:

Re: Cron syntax for bi-weekly server task

 The specifying both day of month and day of week is unsupported.

NOTE: If the month does not have a fifth Wednesday, the task does not run.

Example You can run the task  based on the day to specify.....
Example:  0 0 19 ? * 5#3"

The alternative to specify 3rd Friday of each month (adding "#3")
