• Birthday parties in Russia generally take place on weekends when most people are free to attend. So when one’s birthday falls during the week, it’s best to celebrate the following weekend. 
• They generally last for both lunch and dinner.
•  Russian birthday parties are typically scheduled either for the exact birth date, or a little after it. Russians generally don’t celebrate birthdays before their date, as this is considered bad luck.
•  There is a belief that the person who celebrated birthday in advance, risks not to live up to the actual birth date. It is thought that, on the eve of the birthday one is most weakened, vulnerable to diseases and accidents. Therefore, it is better not to anger your Angels by celebrating in advance.
• Also, to celebrate 40th birthdays is considered a bad omen. According to a Christian belief, on a 40th day after death, one's soul has a judgement day. Because this number is associated with death, its better not to celebrate it. However, a lot of people disregard this in modern Russia.
• In Russia the tradition remains to pull the birthday man's ears by number of the completed years. In old time, people used to pull ears (mainly boys') followed by the saying "Grow up- Don't be noodles". Meaning that the child needs to grow up tall and strong.
