Scheduling a script by using Crontab


I need to schedule a script in crontab which should run at 01:00 am in the morning and should run for every 15 days in a month.

How to schedule this by using crontab?

Many thanks.

I believe most crontabs would accept:
0 1 1-15 * * /path/to/script

This would run on the first 15 days of a given month at 1am.
(I presume this is correct - your definition of "every 15 days a month" is slightly ambiguous)

Thanks citaylor!!!

I mean to ask the script should run once in a fortnight( twice in a month ) at 1am.

0 1 1,15 * * /path/to/script

This will run on day 1 and day 15 of the month
