"I thank all of you. Your wishes mean a lot to me. I will continue to work hard to make Delhi a better city," Dikshit told a group of Congress workers.
The chief minister had to cut several birthday cakes brought by her well-wishers and friends. She was presented bouquets, greeting cards and other gifts.
Dikshit also cut a large cake weighing 75 kgs.
The supporters wished Dikshit victory in the assembly elections slated for November.
"We want you to become chief minister for fourth consecutive term. We are confident of a fourth straight victory in the assembly polls," a group of supporters said.
Assembly Speaker Yoganand Shastri and almost all Congress MLAs visited Dikshit's residence to wish her. A close aide of Dikshit said a number of senior Congress leaders also greeted her.
Dikshit's parliamentary secretary Mukesh Sharma led a youth contingent from his constituency to her residence.
