Nones

The third day before the nones of March is March 5th; the third nones of August is August 3rd; and the third of the nones of November is November 3rd.

Þa monðas þe habbað iiii nonas æfter kalendas... habbað to idus xiii dagas and to ii kalendas eahtatyne. Those months that have 4 nones after the kalends... have 13 days to the ides and eighteen to the second kalends.

Þe caniculer dayes biginnyth in þe fiftenþe kalendis of august and endiþ in þe nonis of septembris, and so þey ben euene fifty as it is seide þere. The canicular days begin on the fifteenth kalends of August [i.e., July 18th] and end on the nones [i.e., 5th] of September, and so they are even fifty as it is said there.

The Roman Month its several days divides By reckoning backwards, Calends, Nones, and Ides.

As for the Nones, it was thought that the multitudes should avoid mass meetings then because after the kings were expelled, the Roman people particularly celebrated what they took to be Servius Tullius's birthday: because crowds notoriously thronged all the Nones—it being well-known that Servius was born on the Nones, though the exact month was uncertain—those in charge of the calendar were afraid that if the whole population gathered on a market day it might start to revolt out of yearning for the king, and so they took the precaution of keeping the Nones and market days distinct.

[March, May, Quintilis, and October] also have their Nones on the seventh, as Numa ordained, because Julius changed nothing about them. As for January, Sextilis, and December, they still have their Nones on the fifth, though they began to have thirty-one days after Caesar added two days to each, and it is nineteen days from their Ides to the following Kalends, because in adding the two days Caesar did not want to insert them before either the Nones or the Ides, lest an unprecedented postponement mar religious observance associated with the Nones or Ides themselves, which have a fixed date.

The interesting thing about these ceremonies is that they must have originated in a period when the Romans were using true lunar months based on the observation of the crescent moon. The Kalends then would have been the day after the evening on which the crescent had been first sighted, the Nones would have been the first day when the moon was at the first quarter... In the calendar of the late Republic the lunar months have disappeared and the days have been fixed into a rigid pattern.

...the same Liturgy of prayers be used both at Nones and Vespers. [With the note:] Nones was what we call three o'clock in the afternoon.

From noon till nones The brethren sate.

The Greek monks always listen to their reader recite Psalms 83, 84, and 85 from the Septuagint at nones.
