run a prog every 15 mins at peak times

[SM777]

Is there an easier way to using crontab for doing this:

run a file every 15 minutes from 08:00 to 11:00, every half hour from 12:00 to 14:00 and every hour from 15:00 to 23:00

I'm just being lazy here. I know I could just type the stuff in in Crontab but just wondering if there is a quicker way especially for the 'every 15 from 08:00 to 11:00'
