How do I book a slot for Bhasma Aarti at Mahakaleshwar?

Bhasma Aarti registration is done online through the official Mahakaleshwar temple website (mahakaleshwar.nic.in). Slots open in advance and fill quickly, especially during Sawan Mondays and Mahashivratri. Book at least 2-3 weeks ahead. On the day of visit, you must report to the designated entry point with your booking confirmation and a valid photo ID.
