After sunset, before nightfall – day or night onah?
September 6, 2009
Question
I got my period in the time of "bein hashmashot". For purposes of the "prisha" days, is that considered daytime or nighttime, or both?? Thank you.
Answer
For the purposes of calculating your onat perishah, the dividing lines are sunrise and sunset. Since your flow began after sunset, even though it was before nightfall, your onat perishah next month is at night.
