Мне нужен перевод (не с переводчика)
Who doesn't like holidays? Holidays
usually mean not going to school or to work, they also mean nice food, present and a lot of fun.
Russian people like them too. Here are some traditional holidays and festivals they celebrate.
1 January – New Year’s Day
14 February – St Valentine’s Day
March or April – Easter Festival
7 January – Christmas
The beginning of a new year is a time for celebrating and for making a new start.
People wish each other "Happy New Year" and send special greeting card. On New Year’s Eve (December 31st) many people go to parties with their families, neighbours and friends. They go to bed after midnight to "see the New Year in” at o’clock. January 1st is a public holiday in Russia. For older people it’s a quiet day in front of the television. But young people go out and meet their friends at parties, discos and different clubs.
On St Valentin’s Day people send a special greeting card (Valentine) to those who they love. It’s a tradition not to give the name of the sender. Some people buy presents for their sweetheats or give them red rose, a symbol of love.
