24 hours. Prosecutors have started sentencing to hours so you only get credit for actual hours you spent in jail.

It really does depend on what county jail we are talking about. Contrary to what Mr. Blum reports, Travis County gives credit for any part of one day spent in Travis County Jail. For example, if you had two days to do and turned yourself in at 11PM and stayed in past midnight, you would be credited for 2 actual days.
I'd recommend talking to your attorney who represented you (or the jail itself) to get more specific information for the county you're going to serve time in.
