Bismillahirrahmanirrahim,
The Hilal (crescent) of Hijri 1436 Jumada al-Akhir has been observed and could not be sighted during the night of March 20th 2015. Since the Hilal could not be sighted, the month Jumada al-Awwal will be completed to 30 days.
Therefore the first day of the Islamic month, Jumada al-Akhir 1436H will be Sunday March 22nd 2015 inshallah.
