12 months
Each quarter contains two 30-day months followed by one 31-day month. Repeating that pattern four times produces 364 days.
Calendar structure
The 364-Day Biblical Calendar Structure
The implemented year contains 12 months arranged as four identical 91-day quarters.
52 complete weeks
364 divides evenly by seven, keeping a complete weekly sequence through the year.
Stable positions
Sabbaths and appointed-time month/day positions remain visible in a repeating structure. Location affects the local dawn boundary, not the month lengths.
Use the calendar
The calendar connects this structure with your selected location, calculates the chosen dawn boundary, marks the current day, and can download the displayed year.
