Sunnah fasting days in August 2020

August 2020 spans Dhu al-Hijjah 1441 – Muharram 1442 AH on the standard Umm al-Qura reckoning. Below is every recommended fasting day in the month with its exact date. If your community's moon sighting runs a day ahead or behind, shift the Hijri dates by one day — the converter and calendar feed both have a ±1 sync setting for exactly this.

20 Dhu al-Hijjah 1441 AH Monday fast

This month also includes the days of Tashreeq (11–13 Dhul Hijjah) — days to celebrate, on which fasting is not allowed. They are left out above by design.

To understand any of these days — the White Days, Mondays & Thursdays, Ashura, Arafah — the blog walks through each one with sources quoted verbatim.
