Counting the Days

"And G-d let her have harayon (conception of a child)." Ruth 4:13

This terse report on Ruth's conceiving and bearing a child whose descendant will be King David serves as a guideline to the length of time between conception and birth.

The gematria (numerical equivalent of the word harayon (hei = 5, reish = 200, yud = 10, vav = 6, nun = 50) is 271, which is the equivalent of nine 30-day months plus one.

If conception did not take place right away, this period could extend to 272 or even 273 days.

Aware of this schedule, the early extremely righteous Jews purposely planned for conception to take place on a day in the week so that the actual birth would not take place on Shabbat and necessitate a violation (though permitted for lifesaving) of the holiness of that day.

  • Nidah 38b

What the Sages Say

"Even those who say that those who give birth in nine months do not give birth before full term agree that those who give birth in seven months such a birth can take place in six months and two days."
