Sighting the new crescent on (Sunday 21 September 2025) and (Monday 22 September 2025) is shown in the below graphs using the program Accurate Times by Mohammad Odeh according to Odeh criterion. Where:-
- It is impossible to see the crescent from the areas located under the red color. Because either the Moon on this day sets before the Sunset and/or the topocentric conjunction occurs after the Sunset.
- The crescent is expected to be seen by optical aid only from the areas located under the blue color.

- The crescent is expected to be easily visible by naked eye from the areas located under the green color.
- The crescent cannot be seen from uncolored areas, even though the Moon sets in these locations after the Sunset and the topocentric conjunction occurs before the Sunset, but the Moon is not sufficiently illuminated in order to be seen as crescent even by optical aid.
- Kindly notice that the below graph shows the possibility of seeing the crescent from areas between 60 degrees north of Equator down to 60 degrees south of Equator.
According to the Universal Hejric Calendar (UHC), which is based on the calculated crescent visibility, the start of this month in the Eastern Region will be on Tuesday 23 September 2025 and in the Western Region will be on Tuesday 23 September 2025. Kindly notice that the UHC is a pre-calculated calendar, which adopts a certain criterion to start the new Hejric month.
