Why are there different dates for Hanuman?

It may just be because each region has its own beliefs for the date. And, anyway, isn't it better to have six birthdays a year instead than one? More cake and gifts!

Why are there different dates for Hanuman?

Basically due to different views on how to keep (calculate) time. Over thousands of years, dates differ very much.

"Senior Indian Astrophysicist Meghnad Saha was the head of the Calendar Reform Committee under the aegis of the Council of Scientific and Industrial Research. Other members of the Committee were: A. C. Banerjee, K. K. Daftari, J. S. Karandikar, Gorakh Prasad, R. V. Vaidya and N. C. Lahiri. It was Saha's effort, which led to the formation of the Committee. The task before the Committee was to prepare an accurate calendar based on scientific study, which could be adopted uniformly throughout India. It was a mammoth task. The Committee had to undertake a detailed study of different calendars prevalent in different parts of the country. There were thirty different calendars. The task was further complicated by the fact that religion and local sentiments were integral to those calendars."
