1. These fast days begin at dawn and end at night, with the appearance of the stars.   One may only eat and drink until dawn, during the night preceeding the fast.  One may only eat if he woke up early before the fast began, if he had planned to rise before dawn to eat.

 

2.  People who are sick do not fast.  Women who are pregnant or nursing do not fast if they feel weak or the fast causes them to suffer.  People who are not fasting should not eat more than is necessary for their health.  This way these people share in the community's mourning.  Children should also not indulge in delicacies.
