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.
An average year is exactly 52.1775 weeks long; months (1/12 year) average at exactly 4.348125 weeks. An ISO week-numbering year (also called ISO year informally) has 52 or 53 full weeks. That is 364 or 371 days instead of the usual 365 or 366 days. The extra week is sometimes referred to as a leap week, although ISO 8601 does not use this term.
