when not to do ekadasi fast - overlaping with dasami

 Oh brahmana, ninety-six minutes before sunrise, if there is an Ekadasi available, it is called a complete and pure Ekadasi. On this Ekadasi, even every householder should fast.

 Even if Ekadasi is available forty-eight minutes before sunrise, still it is said to be mixed with the previous day. People who are interested to increase their merits should give up fasting on such Ekadasis.

 If Dasami day passes over midnight, then one should give up fasting on that Ekadasi, but fast on Dvadasi day.

 Therefore one should give up Ekadasi which is combined with Dasami, even if it is available before sunrise. Specifically, Vaisnavas should always reject Ekadasis which overlap Dasamis.

 One should never fast on the days when Ekadasi is overlapped with Dasami. If one does so, looses whatever merit he had accumulated for one hundred years.

Any person who fasts on the liberating day of Mine, but which is mixed with Dasami, their collective merit for the past 100 cycles (one cycle equals 1000 yugas) is destroyed.

 If there are two people arguing and due to that argument and unsteady opinions the exact date of Ekadasi cannot be determined, then hearing this, one should fast on Dvadasi day and break fast on Trayodasi. This is the scriptural instruction. If any scripture recommends to observe Ekadasi mixed with Dasami, even if Lord Brahma is the writer of that scripture, I (Vyasadeva) do not accept it.

 If there is a reduced day in the fortnight or increase of a day, or if there are three days combined, then one should fast on a pure Dvadasi day and break the fast on Trayodasi

 Srila Sanatana Gosvami remarks in his Digdarsini-tika that if Ekadasi is mixed with the previous day (Dasami), even ninety-six minutes before sunrise, it is said to be an unwanted Ekadasi. It does not matter what moment before sunrise Ekadasi is overlapping Dasami, it should always be given up, especially by Vaisnavas. The duty of a Vaisnava is to reject the mixed Ekadasi of the previous day. Such a statement as this from the Bhavisya Purana is meant specifically for Vaisnavas. It may be found somewhere else that Saivites and others can observe an Ekadasi mixed with the previous day.

 If there is a complete Ekadasi available which begins from dawn and carries on until the next day which, due to extension, continues until sunrise on the next day, it is better to perform Ekadasi on the next day, and this is the duty of both the grhastha and the sannyasi to not follow the previous day Ekadasi.
