Overview
- SUPARCO issued its astronomical forecast on Sept. 11 that underpins the timing, and reports show a minor discrepancy in the new‑moon 'birth' time listed as 8:27 (some outlets report AM and at least one reports PM).
- By sunset on Sept. 12 the agency calculates the moon will be about 34 hours and 33 minutes old, a key measure that improves chances of seeing the thin crescent.
- Along Pakistan’s coastal belt SUPARCO projects a sunset‑to‑moonset interval of roughly 39 minutes, which it says could permit naked‑eye sightings if skies stay clear.
- SUPARCO expects the crescent in inland areas will likely require telescopes, and it frames its forecast as guidance rather than a formal month declaration.
- The Central Ruet‑e‑Hilal Committee must verify credible sighting reports before declaring Rabi‑us‑Sani, so observers, local weather and committee reports will determine whether Sept. 13 becomes the official first day.
