How to get TC to start from 00 at 1 with a countoff barr

I generally like to start my sequences at 0 (bar offset 1). But am always fiddling around with the time code to try and get it to start at the right time. Is there a way to easily figure out the TC necessary to put in the “Start” time so that bar 1 is always at TC 0?

How do I get my sequencer (Cubase Pro ) to start at bar 01? Thanks in advance Peter.
