During the Middle Ages, the time of day seems to have been generally referred to in terms of liturgical hours (matins, laud, etc.) But I've never seen that used in Tudor times.
A summary of a council meeting on August 23, 1545, contains the phrase "...to pray with them for my lord of Suffolk who died yesternight at 4 o'clock." S.J. Gunn says Suffolk died at 4 pm on the afternoon of August 22. But I'm curious as to why 4 pm is considered to be yesternight (italics mine). Did night start at noon and day at midnight? What conventions replaced liturgical hours?
And, if I can sneak in a quick, semi-related question, the council meeting in question was held at Oking where the king (who was on a progress) had moved on August 21 from Guildford. Where or what is Oking? I can't find any mention of it elsewhere.
