Halacha (Jewish law) mandates the use of a Hebrew calendar to calculate the times required to abstain from marital relations in anticipation of a period. The Hebrew date begins at shkiah (sunset) and ends the following day at shkiah (whereas the civil date, based on the standard solar calendar, begins and ends at midnight). All menstrual calculations are figured only according to the Hebrew calendar. Calculations based on any other calendar will not be accurate. Never use the standard solar calendar for this purpose although, for reference only, this online calendar includes the civil dates.

We have seen how the accurate observance of family purity introduces consciousness and communication that help relationships flourish. For this reason, we encourage you to manually track your cycles of separation on a print calendar, using our app to verify calculations and alert you to actions needed.
