Researchers have proposed a solution to the mystery of whether the Qumran sect actually used the 364-day calendar described in the Dead Sea Scrolls. This calendar system organized the year into exactly 52 weeks, ensuring religious holidays fell on the same weekdays each year. However, because 364 days is shorter than the actual solar year of approximately 365.25 days, the calendar would have gradually fallen out of alignment with the seasons over time.


This finding helps historians better understand the religious practices and daily life of the Qumran community, which produced the Dead Sea Scrolls around 2,000 years ago. It resolves a longstanding debate about whether this unique calendar was purely theoretical or actually implemented in practice.

Researchers may have solved a long-running mystery surrounding the Dead Sea Scrolls by proposing that the Qumran sect really did use its distinctive 364-day calendar. Its perfectly ordered 52-week system kept holidays on the same weekdays, but it slowly drifted out of sync with the seasons because it was shorter than the true solar year.
