Mahayana Buddhists celebrate Mahaparinirvana Day, or Nirvana Day, on the second full moon of the lunar calendar to commemorate the Buddha’s death, or transition to Mahaparinirvana. At that time, temples and centers read the Mahaparinirvana Sutra, which tells of the Buddha’s last days, recite and meditate on the impermanence of all phenomena. Japanese Buddhists celebrate Nirvana Day according to the solar calendar, every year on February 15.
