ISNA Moonsighting calculations

I am not opposed to using calculations for the purpose of moon sighting.
But, why use a methodology that is so blatantly incorrect?

ISNA has already declared 1st Ramadan as July 9th and Eid as August 8th.
ISNA Announces Ramadan Dates - ISNA

Look at the visibility curves for these dates and you can see that there is no possibility of sighting the moon on the evenings previous to these dates.

Re: ISNA Moonsighting calculations

See..i don't understand ISNA at all as well as ppl who go with Global Moon Sighting. We go by Hilal committee here and so as majority of masajids here.

Re: ISNA Moonsighting calculations

Hilal committee is supposed to meet after Maghrib and decide on moonsighting/confirmed started of Ramadan tonight for the Chicago area.

MCC/MEC have noted on their Prayer Schedule for the first fast to be on Wednesday July 10th, 2013.
