Q: Is there a time limit for going to the temple to worship Buddha?

There is no time limit. It is good luck to go to worship Buddha and burn incense at any time.

However, during Buddhist festivals, or on the 15th of each month, there are more pilgrims who go to temples to burn incense. Moreover, in Buddhist festivals, temples will hold Dharma meetings, so it is better to attend the Dharma meetings of temples as you like when going to Buddhist festivals.
