Dead Sea Scroll Remains a Puzzle After Scientists Crack its Code

Scholars have deciphered a Dead Sea Scroll written in a Hebrew code, finding that it contains part of a 364-day calendar of holy days.
The calendar notes the day of Sabbaths, the start of seasons and the days of festivals and feasts. The scribe, who went to the trouble of writing the scroll in code, forgot to include the Day of Atonement (known as Yom Kippur) on the calendar; but another scribe, who apparently understood the code, inserted that day onto the calendar.
