As well, secretaries do not often have the authority to make appointments for their bosses. Another tip would be to follow the news paper since it shows all the prayer times for that day.
If one is able to set up a business appointment at a restaurant or home there are also rules that apply, muslims do not eat pork because its against it's against their religion, and any other meat needs to be halal which means it is permitted or lawful according to the Qu'ran dietary guidelines. No pork or pork by products, no animals that were dead before slaughtering, no animals who were not slaughtered in the name of allah and no blood and blood by products.
