Ramadhaan & Fasting

When to Sight the Moon?

Q: We have a muslim business manager who has decided that Sunday will be Eid. Since when has Allah given this man the authority to decide that Ramadhaan will only be 29 days? We have now been told that we cannot put in leave for Monday we must wait until friday. So I said but they will only do the moonsighting on Saturday and not Friday as Saturday is the 29 day of ramadhaan. 

Waiting till Zawaal While in Haidh to Fast in Ramadhaan

Q: You stated that a sister should commence with fasting before fajr time has entered. If I did not misunderstand is that the case with nafl? I wanted to clarify if there is any difference in Ramadan. We read in Turkish kitabs that in Ramadan we should wait until zawaal with fasting and if we are sure that we are clean before zawaal and haidh has ended, then ghusl should be taken and make niyyat and fast. Please correct me if I understood wrong because I was practicing on that.
