Referencing a book called Psychotropic Drugs and Women: Fast Facts by Hendrick & Gitlin...under "rapidity of effect" with the options being rapid, intermediate or slow...both are intermediate. Klonopin has a longer half life though. Personally, I do well with Ativan but was tired all the time on Klonopin.

There is a chart about equivalent doses of benzodiazapines
.5 mg ativan is = to .25-.5 of Klonopin.

Usual daily dose of Ativan is 1-6 mg (although I only take .5-1 mg and it works well even after being on it for many years) and for Klonopin it is .5- 3 mg

I have to wonder though, why on earth do you have two prescriptions for benzos? That is not something most doctors would prescribe at the same time. I certainly would not recommend taking more than one benzo at a time without explicit instructions (and a solid, sensible explanation of why) from a doctor to do so.

Asker's Comment:
Thank you for your help. The doctor prescribed me on the Ativan in May, & it was supposed to be a daily dose. I didn't feel right taking it daily, so I stopped. Then I went in for panic attacks, & he prescribed me the klonopin as needed for anxiety. So that's why I have a prescription for both.
Steve gave you the best Answer. Klonopin's half-life is pretty much the whole day, while Ativan on the other hand has a shorter acting half-life. I tried both Ativan and Klonopin. maybe the doctor gave you a low amount of quantity on both for him to see which works better I presume. I'm on 1mg 3xday
