Why Mahashivratri 2026 will be celebrated on Feb 17, Not Feb 15?

Mahashivratri in 2026 will be observed on Tuesday, February 17, not February 15, as per the Hindu Panchang. The Phalgun Krishna Paksha Chaturdashi Tithi begins at 8:41 PM on February 17 and ends on February 18, making February 17 the correct day for night-long worship, fasting, and rituals dedicated to Lord Shiva.
