The government portal gives a morning session from 7:30 am to 1 pm. Its afternoon information conflicts by thirty minutes, stating both 3 pm and 3:30 pm as reopening before 7:30 pm darshan and closing activity to 8 pm.
What the record supports
That inconsistency should be shown rather than silently resolved. The same portal lists individual pujas and service prices, which are separate from ordinary darshan and may change.
Make the visit work
Aim well inside a confirmed session, call locally if arriving in the afternoon and leave extra time for a queue. Remove footwear where directed, carry minimal baggage and ask about services before paying.
