The crontab format is described in section 5 (file formats) of the manual. With most man implementations for Linux, you do:
man 5 crontab
to read it (on some systems, you need man -s 5 man instead). man crontab would give you the manual of the crontab command (in section 1 of the manual). See man man for more information.
While historically, you'd have needed:
0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58 * * * * /path/to/script
(every 2 minutes starting at 00:00:00)
or
1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39,41,43,45,47,49,51,53,55,57,59 * * * * /path/to/script
(every 2 minutes starting at 00:01:00)
With modern cron implementations (including the ones typically found on Linux distributions), you can simplify it to:
*/2 * * * * /path/to/script
1-59/2 * * * * /path/to/script
If you want to run it every 2 minutes starting at 00:00:34, you can always write it:
*/2 * * * * sleep 34; /path/to/script
