I am trying to setup a cron job on a Ubuntu server. We want the cron job to run the script at certain times of the day and on some specific days of the week. For example, we want to setup a cron job that runs the script with the following sequence:
Execute the script every 2 minutes from 9 am to 2 pm during the weekdays.
This is what I have been able to do so far:
*/2 09-14 * * * /path_to_script
What should I do for the weekdays?

The basic usage of cron is to execute a job in a specific time as shown below. This will execute the Full backup shell script (full-backup) on 10th June 08:30 AM. Please note that the time field uses 24 hours format. So, for 8 AM use 8, and for 8 PM use 20.
Thankfully, you can configure a specific timezone for your Cron job as follows: First, you need to export the TZ variable in your Shell script before any other Shell entries. Next, access your crontab and use the crontab environment variable CRON_TZ at the start of the crontab file.
Same as you did for hours:
*/2 09-18 * * 1-5 /path_to_script 0 and 7 stand for Sunday6 stands for Saturday
so, 1-5 means from Monday to Friday
120
You state 2pm in your requirement, hour range should end at 14 instead of 18 (which is 6pm).
*/2 9-14 * * 1-5 /path_to_script man crontab
