Under the early English common law, ownership of real property was transferred by a technique called âfeoffment.â This involved delivery of possession, which was termed âlivery of seizin.â No writing or deed was involved.
On average there are about 4.3 weeks in a month. Each week is 7 days, and there are normally either 30 or 31 days in a month, so there are usually between 4.2 and 4.4 weeks per month. The exception is February because it has fewer days, so there are about 4 weeks in that month.
In a cycle, there are 7 x 400 = 2800 months of 31 days, there are 4 x 400 = 1600 months of 30 days, there are 300 +3 = 303 months of 28 days, and there are 100 - 3 = 97 months of 29 days. Taking the weighted mean, the average number of days in a month is (2800 x 31 + 1600 x 30 + 303 x 28 + 97 x 29) / 4800 = 30.436875 days exactly.
