Birthday party

Hello, Today is Saturday but there in your country is still Friday. Yesterday evening I went to my friend's birthday party at Bar beer night club. It  is located  not far form my office next to the main road. I arrived there almost at 20.00. and I was so surprised  to see thousands of people in there. That was the real night life style. They went there to  drink and dance. It is different from my life style because after work I go to the gym and back home afterwards. This is my good experience to learn the real night life style in the capital city which  is quite different from  my home town. The bar beer night club closed at 02.00 hours. I feel free and very happy to take a rest for a long time (?) at the  weekend.

Usually when you wrote a time "20.00" you don't need to add word hour. Or you can write 8pm.
