Ruling of non-Muslim Fasting
Question

                When is the month of Ramadan and can someone like me fast properly? What time 
of the day am I supposed to fast?
Praise be to Allah.The fact that you have concern with the blessed month of Ramadhan, are questioning it's arrival, 
and anticipating it, is very wonderful. It indicates that you are affected by this great Islamic 
worship, which consists of abstaining from food and drink, and sexual intercourse from fajr (the 
break of dawn), until maghrib ( the sunset) during the day of the noble month of Ramadhan.
As far as it's appointed time, my dear respected questioner, the laws of worship in Islam are 
scheduled according to proof which is clearly traceable and detectable. The evidence which is 
seen is not estimated. This entails the sighting of the moon, which indicates that the month of 
Ramadhan has begun. So, if we see the new moon, or it is established that someone amongst us 
has seen the new moon, then it becomes obligatory on the entire Muslim community to fast every 
day of this month, until we see the new moon for the following month of Shawwal and know that 
therefore Ramadhan has ended.
The month of Ramadhan on the Islamic calendar could be 29 or 30 days depending on the 
sighting of the physical proof, which is the new moon. According to the Christian calender, the 
approximate time of Ramadhan this year would occur on the 30th or 31st of December 1997.
In order for your fast to be correct and accepted, you must first enter Islam by testifying to 
Allah's Oneness and believing in the Prophet and following the laws of Islam. We would be 
happy to see you living a happy life with strong faith, and good years to come, spending them 
inspired by Islam. We ask Allah to protect you and guide you along.
