Python Script vs Cron Job

I need to run a cron job to generate a list of user rankings each week at exactly "00:00:00" UTC each Monday morning. Has anyone got an example for this, it's really doing my head in ... I looked into "crontab -e" and was instantly lost.

Basics:
 - Run the script, eg: /srv/django/get_rankings.py
 - Run the script at "00:00:00" and "00:05:00" every Monday.
 - Run the same script the next Monday ... and repeat

I'm on Linux Arch, any heads up would be amazing.

Thanks so much, Hope all is well

crontab put entry like,

00,05 0 * * 1 /srv/django/get_rankings.py

runs the script at 00.00 & 00.05 every Monday of every month

*     *     *   *    *        command to be executed
-     -     -   -    -
|     |     |   |    |
|     |     |   |    +----- day of week (0 - 6) (Sunday=0)
|     |     |   +------- month (1 - 12)
|     |     +--------- day of        month (1 - 31)
|     +----------- hour (0 - 23)
+------------- min (0 - 59)

* in the value field above means all legal values as in braces for that column. The value column can have a * or a list of elements separated by commas.

An element is either a number in the ranges shown above or two numbers in the range separated by a hyphen (meaning an inclusive range)

crontab -e, and insert these:

0 0 * * 1 /srv/django/get_rankings.py
0 5 * * 1 /srv/django/get_rankings.py

0 0 is midnight; 0 5 is 05:00am. 1 is Monday. The two stars mean "I don't care about the date". Here is a good reference.

You can put it all in one line by saying "0 o'clock or 5 o'clock":

0,5 0 * * 1 /srv/django/get_rankings.py
