While the most important Shivratri is the Mahashivratri observance in February/March, the monthly observances also hold significance in their own way. As we enter New Year 2023, one must know the Masik Shivratri 2023 dates to prepare for this auspicious occasion. The first Masik Shivratri 2023 will be observed on January 20, and Mahashivratri 2023 falls on February 18.
