Each tekufa, according to Samuel Yarḥinai, marks the beginning of a period of 91 days and 7½ hours. It will be noticed that the tekufot fall from fourteen to eighteen days later than the true solar equinox or solstice; this, however, does not interfere with the calendar, which follows the figures of R. Ada.

Superstition

An ancient superstition is connected with the tekufot. All water that may be in the house or stored away in vessels in the first hour of the tekufa is thrown away in the belief that the water is then poisoned, and if drunk would cause swelling of the body, sickness, and sometimes death. Several reasons are advanced for this. Some say it is because the angels who protect the water change guard at the tekufa and leave it unwatched for a short time. Others say that Cancer

, however, warns his co-religionists to pay no attention to ibn Ezra's remarks, asserting that in his own times many persons who drank water when the tekufa occurred fell ill and died in consequence. Da Silva says the principal danger lies in the first tekufa (Nisan), and a special announcement of its occurrence was made by the beadle of the congregation (Peri Ḥadash, on Oraḥ Ḥayyim, 428, end). The danger lurks only in unused water, not in water that has been boiled or used in salting or pickling. The danger in unused water may be avoided by putting in it a piece of iron or an iron vessel (Bet Yosef on the Tur
