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.

The proper way to observe Vaisnava festivals, for example, Ekadasi, Varaha-dvadasi, and Nityananda Trayodasi is as follows:

In countries or cities where the first day is Ekadasi, the second day is the appearance of Lord Varahadeva, and the third day is the appearance day of Lord Nityananda (Nityananda Trayodasi), for both those who follow nirjala Ekadasi (full fasting, even from water) and those who follow anukalpa (respecting Ekadasi preparations) on Ekadasi tithi: on the next day they should first offer arati to Lord Varahadeva, pray for forgiveness*[see endnote 1], and then break the fast* [see endnote 2] with grains and continue to respect regular prasadam (grains and all other offerings). Then, on the third day - Sri Nityananda Trayodasi - they should observe the Ekadasi rules and regulations.

In countries or cities where the day after Ekadasi is both the appearance of Lord Varahadeva and Sri Nityananda Trayodasi, the devotees who follow nirjala Ekadasi, can break their Ekadasi fast by drinking water on the next day, and for the rest of the day respect anukalpa (regular Ekadasi preparations).

For those devotees who respect Ekadasi in the regular manner (respecting offerings of anukalpa), the next day they should first offer arati to Lord Varahadeva and Lord Nityananda, then hear Their glories. After this they should pray for forgiveness*[see endnote 1] and then they may break their fast by taking grains. The rest of the day they may respect regular prasadam.

*[Endnote 1 – generally the appearance day of Lord Varahadeva, as with any incarnation’s appearance day, is observed by taking only ekadasi preparations.

*[Endnote 2 – to know the exact time of breaking the fast for your city, please check theVaisnava calendar.
