The Electronic Zadok Calendar is a calendar designed for those who follow or study the 364-day Zadokite calendar discussed in scripture, the book of Jubilees, the book of Enoch, and preserved in the Dead Sea Scrolls.

Rather than requiring you to calculate the Zadok calendar date each day, this electronic calendar keeps the current Zadok date visible at a glance. The display shows the feast or appointed time when applicable, the Zadok calendar date, and the day of the week. Sabbaths and biblical feast days are clearly identified so you can quickly see where you are in the calendar year.

The calendar is built around the 364-day Zadok calendar, in which the year begins on the fourth day of the week and the annual cycle remains aligned with complete weeks. Its software automatically determines the appropriate beginning of the Zadok year using the spring equinox and advances the calendar accordingly.

The E-Ink display gives the calendar the appearance of printed text while using very little power and remaining easy to read throughout the day. There are no distracting animations or constantly glowing screens—just a simple display of the biblical calendar.

The calendar includes the appointed times found in Leviticus 23, including Passover, the Feast of Unleavened Bread, Shavuot, Yom Teruah, Yom Kippur, and Sukkot, as well as Second Passover.

Each calendar is assembled and programmed by Watchmen of Israel as a practical tool for studying and observing the Zadok calendar.

Whether you are already following the Zadokite calendar, studying the Dead Sea Scrolls, researching the 364-day biblical calendar, or simply looking for an easier way to keep track of the appointed times, the Electronic Zadok Calendar provides a simple physical reference you can keep on your desk, shelf, or study area.
