The Muslim World League (MWL) standard defines Fajr (dawn) at 18° below the horizon, and Isha at 17° in the evening, signaling the onset of complete darkness for your local Arneiro coordinates.

While both use 18° for Fajr, the University of Islamic Sciences in Karachi uses a more symmetrical 18° for Isha as well. This usually results in a slightly later Isha time compared to the MWL standard in Arneiro.

In northern or high-latitude cities where the sun may not reach 18° below the horizon during summer, the MWL method often utilizes adjustments to ensure prayer times remain manageable for the local community.
