When do seven days start?
11 December, 2002
Do I have to do a Hefsek Tahara in the evening, and start 7 days the next am, or can I start in the morning with a bedika? Thanks.
In order to begin the seven clean days, you first need to do a hefsek taharah. This exam is done as soon as you have stopped bleeding, no earlier than the fifth day since you became niddah (counting the day on which you became niddah as day one). The hefsek taharah must be performed BEFORE sunset. The seven days actually start in the evening AFTER sunset (as the Hebrew "day" starts at night).
Bedikot are only done during daylight (between sunrise and sunset). Thus, the first bedikah is done the next morning. You do bedikot on each of the seven days following the day on which you did the hefsek (NOT including the day of the hefsek). You then go to the mikveh the night after the seven days are over.
For example, if you did a hefsek taharah on Wednesday afternoon before sunset, then you would go to the mikveh one week later on Wednesday night.
