I'll answer this question in a generalised way. Like anyone else birthdays should celebrared in a grandeur way with lots of fun a nd surprises. Of course .... birthday with a party and cake cutting is a must. Shopping of goodies and eatables for the party. Inviting friends fot the party. Surprises and games are optional too!
I celebrate my birthday in a simple way. I get up early.I wear my new clothes.
I get blessings from my parents. After that, I go to temple.Friends and  relatives wish me .I receive gifts from them. Mom prepares my favorite dishes. I would get whatever i want. I plant a plant symbolically on every birthday. In the evening, I give a small party .
