How would I use crontab to run a script at 5:30AM every other Friday in January? This is the what I have if I ran it every Friday. 

30 5 * 1 5

If I did every other friday, where do i put the /2? Is it:

30 5 */2 1 5

or:

30 5 * 1 5/2

check this solution here but I would recommend using two crons one for the first week and second for the third week as mentioned here.You could als use http://www.cronmaker.com/ to build crons.Hope it helps.

Try this

0 0 1-7,15-21 * 5

This is run 2 times a month, both on Fridays and at least a week apart.

  • This can backfire depending on the cron service. It executes at **00:00 on every day-of-month from 1 through 7 and every day-of-month from 15 through 21 and on Friday** on many services. Try different combos at [crontab.guru](https://crontab.guru/#0_0_1-7,15-21_*_5). – Richard Nov 07 '21 at 03:29
  • @Richard it worked for me, still running on my production server, no issues till now. I don't agree that it'll fail in any case. – Wolfack Nov 10 '21 at 12:09
