Depending on what part of Calabasas you live and where exactly in Pasadena you will be working, I would give it a good 60 to 75 minutes. You will need to drive a couple different routes depending on the time of day you go to work and back, but my suggestion is to definitely try the 118 to 210 route, vs. the 101 to 134 route due to heavy congestion.
There are a lot of other nice areas much close to Pasadena that have nice homes for a really good price. I was showing some homes in Alhambra and burbank today.
Please let me know if you need a good realtor to find you the right home at the right price.
