ISNA Fiqh Council fixed dates for N. America (fixed by the "New Moon before 12:00Noon GMT") are:

            Ramadan 1428                     September 13        (Begins from the sunset on Sep. 12)

            Eid al-Fitr                             October 12             (Friday)

            Eid al-Adha                          December 20         (Thursday)

Saudi dates in Ummal-Qura calendar (fixed by the "New Moon date + moonset after sunset in Makkah") are:

            Ramadan 1428                      September 13        (Begins from the sunset on Sep. 12)

            Eid al-Fitr                              October 13             (Saturday)

            Eid al-Adha                           December 20         (Thursday)

Do these dates fulfill the Shariah requirement of a visible Hilal? Actually NONE.  ISNA Fiqh Council says that “Seeing the Moon” (Ru’ya) is not required by the Shari’ah.

The Hilal cannot be seen in the USA, Canada or Makkah on Wednesday, September 12. Its altitude is too low. It will be easily visible on Thursday evening, making Friday, Sep 14, the first date of Ramadan. (In South Africa and South America it may be visible on Sep. 12)

Shawwal moon will be visible only in South America (and southern USA??) on Friday, October 12. For most of the USA, Canada and Makkah the most likely Eid date is Sunday Oct. 14.

D. Hijjah Hilal is likely to be seen on December 11 in most of the world (except December 10 in South America). The moon is too far south to become visible in the northern hemisphere on December 9 or 10. Based on the moon’s probable visibility in Saudi Arabia, Hajj date in Makkah should be December 20.
