About this prediction

A guide for your region

This calendar uses astronomical calculations and the Odeh crescent-visibility criterion to estimate where the first visible crescent may be seen with the unaided eye. By prediction, only Odeh Zone A begins New Moon Day. If a person actually witnesses the crescent on an earlier Zone B evening, they may apply that sighting to update New Moon Day and the four Sabbaths for their selected region. Actual visibility can be affected by cloud, haze, the local horizon, eyesight and observing conditions.

A witnessed-sighting choice is stored only on that person’s device for the selected location and lunar month. It remains separate from the prediction and is not submitted as a shared or independently verified observation report.
