This resource provides detailed information on:

• First Visibility Dates
  Projected dates when the hilal (lunar crescent) is first expected to be seen from Brunei’s skies when it is above the horizon, based on astronomical calculations.
• Sighting Predictions
  Each lunation includes prediction on the crescent’s visibility probability, V, developed by Mohammad Shawkat Odeh (2005) across Brunei. The neo-MABIMS visibility criteria (Alt ≥ 3°, Elong ≥6.4°) is also indicated by Y (satisfy) and N (does not meet).
