- Red letter day
A red letter day (sometimes
hyphenated as red-letter day or called scarlet dayin academia) is any day of special significance.
The term originates from
Medievalchurch calendars. Illuminated manuscripts often marked initial capitals and highlighted words in red ink, known as rubrics. The First Council of Nicaeain 325 decreed the saint's days, feasts and other holy days, which came to be printed on church calendars in red. The term came into wider usage with the appearance in 1549 of the first Book of Common Prayerin which the calendar showed special holy days in red ink.
On red letter days, judges of the English High Court (Queen's Bench Division) wear, at sittings of the Court of Law, their scarlet
robes (See court dress). Also in the United Kingdom, other civil dates have been added to the original religious dates. These include anniversaries of the Monarch's birthday, official birthday, accession and coronation.
In the universities of the UK, red letter days are called scarlet days. On such days, doctors of the university may wear their scarlet 'festal' or full dress gowns instead of their undress ('black') gown. This is more significant for the ancient universities such as Oxford and Cambridge where
academic dressis worn almost daily; the black undress gown being worn on normal occasions as opposed to the bright red gowns. Since most universities now only use academic dress on graduation day (where doctors wear always scarlet), the significance of scarlet days has all but disappeared.
The term "red letter day" is colloquially used to indicate any date of personal significance.
In Sweden and South Korea, a public holiday is typically referred to as "red day" (röd dag, 빨간 날), as it is printed in red in calendars.
"Red letter day" was a 19th century naval term used to distinguish between gunpowder charges used for gunnery practice stored in boxes marked with black letters and the more powerful charges used for engagement, marked with red letters.Verify source|date=July 2007
