The white days are 3 days of the Hijri month during which fasting is strongly recommended. Imam Tirmidhi reports that the Prophet Muhammad - that peace be upon him - he said "If you want to fast three days a month, fast on the 13th, 14th and 15th day." Obviously he was talking about the lunar months of the Muslim calendar. Not the days of September.
