Sunnah fasting days in March 2023

March 2023 spans Sha'ban 1444 – Ramadan 1444 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.

Part of March 2023 falls in Ramadan, when the whole month's fast is obligatory — so no extra sunnah fasting days are listed for those dates, and our reminders pause too.

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