My Watch

Recently I was in a place where there were radical temperature changes between day (hot) and night (cold). The temperature changes affected my watch. I noticed that it was minute fast at nightfall, but at dawn, it has lost 1/3 of a minute, making it only 1/6 of a minute fast. If my watch was exactly correct on March 1 and I stayed in this location for over a month, when would my watch be exactly 5 minutes fast?
