The plans for this New Year

This year the Dec 30th and the Dec 31th are the working days. The school holidays of my son will begin on the Dec 28th. My son and my wife are going to country house with a car with all stuff. I will come to them on the Dec 31st only. I am going to get to the country house by the train. The way to there takes about 3 hours. If I want to meet New Year with my family I'll need to go out from my work no later than 7 pm. My wife or my father-in-law usually meet me on the train station. I think, maybe we can do all our work for the holiday week ahead and make the Dec 31th the day off. Then I could go to country house on the Dec 30th and exactly wouldn't be late.
