How to read the map?
Pick the month in the dropdown: the next lunation is already selected.
Locate your region and note its letter: A = crescent visible to the naked eye, B = visible with optical aid and sometimes to the naked eye, C = visible only with optical aid, D = not visible.
Drag the timeline below the map: the crescent is only observable between sunset and moonset, in the band that moves westward hour by hour.
Calculation method
The calculation applies the criterion by Muhammad Odeh (2004): the apparent angular separation between the sun and the moon (ARCL), the difference in altitude between the two bodies (ARCV) and the width of the crescent (W), evaluated at the best observing time after sunset. Classes A to D follow the visibility zones of the criterion. The world grid is spaced at 2 degrees.
