Deciding on the Moon

Re: Deciding on the Moon

ISNA is better. It just tells you the day when moon will be visible. If the calculations are correct, there is no way you could see moon before that. If the calculations are not correct, ... improve them.

So they are not really taking away "seeing the moon" part. They are just telling you, when u be able to see it. Its like weather forecast, only that weather forcast cannot always be very accurate, because of far too many variables. However moon orbit and speed is fixed, so its much much easier.
