HOW IT WORKS

1. Set Your Anchor: Choose a known Biblical date (e.g., "Month 1, Day 1 = today") to establish your calendar starting point.

2. Track New Moons: On days 29/30 of each month, the app prompts you to confirm if the new moon was seen. When confirmed, it records the next month start.

3. Determine the Year: On day 29 of month 12, confirm if barley is aviv to determine whether the year has 12 or 13 months.

4. View Your Calendar: See projected months and feast days in the calendar view, which updates as you confirm actual month starts.
