Lord Varaha

Gaudiya Vaisnavas observe all visnu-tattva appearance days along with special fasting. Sometimes these days come next to each other or next to an Ekadasi or Dvadasi tithi which is meant for fasting. This happens every year somewhere in the world for Lord Varaha Dvadasi and Lord Nityananda Trayodasi, but not at all locations due to different sunrise times.
