I have observed the moon yesterday and today (Thursday and Friday) at sun rise.
Yesterday the angular distance was 95 degrees and today 83 degrees. The average is about 12 degrees. This indicated that this month has 30 days. The first crescent was seen on Wednesday the first of this month. The moon and sun will be in the same Manazil on Thursday. The last crescent will be seen on Wednesday morning and Rajab begins on Friday.
According to the phases of the moon both Rajab and Shaban have 29 days only. Ramadan will begin on Sunday and fasting must commence from Sunday. What do the astronomers say about this?
