About this calendar

This free calendar counts from the day the niddah state began and marks, on the Hebrew calendar, the five minimum days, the hefsek tahara before sunset, the seven white days and the night of immersion in the mikveh.

To use it, touch the grey part of that date if it began at night, or the white part if it began during the day. If the hefsek tahara was done on a later day, choose “The hefsek tahara was later” and touch that day. Separation dates (vestos) are not calculated here yet.

For any practical question, please ask an orthodox rabbi expert in these laws, or ask Rabbi Jacobs.
