\n However...

\n However, there have appeared some Ahadith during the Major Occultation (Ghaibah e Qubra), which suggest that the Month of Ramazan can be deficient (29 days) as well as complete (30), see Appendix II.\u00a0 The Ahadith in Appendix II, are compiled from Wasail ul Shia, and contain both types of Ahadith that the month of Ramazan can never be deficient but will always be of 30 days as well as it can be of 29 days.\u00a0 As, we will see later, the latter ones can be out of strict conditions of Taqeeya during the caliphate of Bani Ummayya and Bani Abbas [2] .\u00a0 Also, there is evidence that the certain months will be complete (30 days).\u00a0 We also find in Ahadith (Appendix II) that one must Fast to complete the 30 Fasts if the sky is overcast but one must never Fast on the 1 st of Shawwal, in agreement with all other Ahadith that one must not Fast on the day of Eid ul Fitr.\u00a0 Hence the importance of starting the Month of Ramazan on a day that ensures one will complete the 30 Fasts and not less.\u00a0 This highlights the importance of the calculations (i.e., for Shawwal crescent) in those countries where skies are overcast most of the year.
