The Metric month is the four-week period of the Quaternary Metric World Calendar which lasts 28 days, with the exception of Equatorial Month (of which the compass name is Central Month) in the middle of the year and, once every four years, Southern Late Lent (Late Southwest Month) at the end of the year, which last 29 days and have one eight-day week (the second in Equinoctial and the fourth in Southern Late Lent). Every such month one idea, aphorism or statement receives special attention in a trailer of the main document. It is called "the Note of the Metric Month". Such a 'note' may be serious or profound at one time and funny or light-hearted at another — it just can't be predicted.

Until the 57th year after the end of the Second World War (that is, the year 57 inclusive) the Notes of the Metric Months were put together in one file. As this file was getting too long, they are now collected in files which cover four years, that is, 52 notes. The first ASWW year of each file is divisible by four. The collection starts with the note of the 52nd Southern Mid-Yule (MSE).

The current eight documents attached to this branch of Notes follow in chronological order below. Where the titles of the separate Notes are mentioned as well, they are being listed in alphabetical order, apart from the or a(n). (The number after the title, between 1 and 52, is the number of the Note in the document in which it appears.)
