Here is the challenge – Whatโs the youngest moon you can see this year? The infographic will tell you when to hunt the new moon crescent (hilal), and where to locate its position in the western sky at sunset from Brunei Darussalam in 2020.
Note: Prediction method by Mohammad SH. Odeh (New Criterion For Lunar Crescent Visibility, 2005) employed new criterion visibility of the lunar crescent, V. This is only a computational analysis data. The result/declaration of the sighting/beginning of hijrah month should be referenced to official media by the Government.
Itโs rare and very challenging to see a moon within 24 hours of new moon. Our PABD include monthly hilal observation to spot the youngest possible moons with digital camera, optical aid, or with the eye alone.

Prediction method by Mohammad SH. Odeh (New Criterion For Lunar Crescent Visibility, 2005) employed visibility of the lunar crescent by this new criterion, V= ARCVโ(โ0.1018W3 +0.7319W2 โ6.3226W +7.1651) where: ARCV: Airless and topocentric arc of vision in degrees. W: Topocentric crescent width in arc minutes ;
V > 5.65 : Naked Eyes
2 < V < 5.65 : Optical aid / Naked eyes
-0.96 < V < 2 : Optical aid only
V < -0.96 : Not visible
