How the biblical calendar works
Months are lunar, years remain aligned with the agricultural seasons, and days are reckoned from evening to evening.
Read Genesis 1:14 ↗Follow the Hebrew date, the moon’s rhythm, and the sunset boundary that carries one sacred day into the next.
YadHub displays today’s standard fixed Hebrew calendar while also explaining the observational and agricultural language found in the biblical texts.
Months are lunar, years remain aligned with the agricultural seasons, and days are reckoned from evening to evening.
Read Genesis 1:14 ↗The lunar cycle is about 29½ days. Its visible phases provide a memorable rhythm, though the fixed calendar uses calculation.
Read Psalm 104:19 ↗The mo’adim join dates to memory, worship, harvest, justice, and hope—forming a yearly teaching cycle.
Read Leviticus 23 ↗Each observance links a calendar date to a scriptural story and a living Jewish practice.

“Biblical calendar” can refer to different reconstruction methods. YadHub will never silently mix the modern fixed Jewish calendar with proposed sighting-based systems. Every displayed method will be named.
