When does the feast of unleavened bread start and end?
Answer From The Annual Reading Schedule - Week 16 Notes For Exodus: According to Exodus 12:18, we eat unleavened bread from the 14th day in the evening until the 21st day of the month in the evening. It does not go morning to morning. It starts in the evening and it ends in the evening. Also: Ezekiel 46:1-2 shows it's impossible for days to ever begin in the morning. The reason manna (Hebrew – Man) was instructed to be kept until morning is more indicating the limited night time hours probably in the desert. With limited night-time hours when it is cool, those hours were probably only used, or primarily used, for sleeping; probably not likely those hours were used normally for the majority of cooking and eating when sleep is needed during the hours that it's dark and cooler. Remember, they had no air conditioning in the desert. So as soon as the sun was down, they are more likely to have gone to sleep. So the natural instruction would be to keep it until the morning because all cooking and eating is likely finished by sunset because it's much easier in the day time to cook and eat. Then, after the sun set, they slept, then woke, and could eat more in the day time in the morning. Instructing the Yisra'elites (Israelites) to keep manna until morning doesn't definitely prove when a day starts and could just reflect the fact that it wasn't normal to cook at night anyhow if those dark, cooler hours were limited and needed to be taken advantage of for sleep instead. Ezekiel 46:1-2 actually does prove definitively when the "six days of work" begin – and that is in the evening – with no alternative explanation possible.
