If it is on Sep 6th Than you will have to do the dar khane which is a midnight meal on 5th, just before 6th starts. Usually dar khane tradition is done at borthers or parents place. So on 6th you are not supposed to eat anything I think you cannot even drink water until next day. I was home last year during teez and I saw women went to the near by temple including my mom with all their gahanas and bright red sarees and dance and had so much fun on fasting day. I have never took teez fasting eaither but I have mentioned above whatever i saw last year at home. Have a great TEEZ!!!!!!!!!!!
