An Elven day is called a of which a yén contains 52,596. An Elven week, used for ritual rather than practicality, contains six days and is called enquië; and a yén contains 8,766 of these enquier.

The Third Age is a time period from J. R. R. Tolkien's Middle-earth fantasy writings. The history of Middle-earth is to be taken fictionally as a history of the real Earth....

. Therefore, years of the Third Age can be converted to Shire-years by subtracting 1600. The last year of the Third Age was year 1421 on the Shire calendar. A year in the Shire was the same length as our year - 365 days, 5 hours, 48 minutes, 46 seconds. The Shire's calendar year was also divided into 12 months but all of 30 days. Five additional days were added to create a 365-day year. The months followed the lunar cycle.

For the names of the months, Tolkien used reconstructed names derived from Old English; in other words, they are Tolkien's take on what Modern English would have actually used if it had not adopted Latin names for the months (January, February, March, etc.).

The Yuledays were the days that signify the end of an old year and the beginning of a new one, so 2 Yule was the first day of the year. The Lithedays are the three days in the middle of the year, 1 Lithe, Mid-year's Day, and 2 Lithe. In leap years (every fourth year except centennial years) a day was added after Mid-year's Day called Overlithe. All these days were placed outside of any month. These days were primarily holidays and feast days. Mid-year's Day is meant to correspond to the summer solstice
Solstice
A solstice is an astronomical event that happens twice each year when the Sun's apparent position in the sky, as viewed from Earth, reaches its northernmost or southernmost extremes...

, which Tolkien describes as being 10 days earlier than the middle day of our year. However, since then the summer solstice has shifted slightly so it falls on a different date now, rendering the difference between Mid-year's Day and the middle day of our year eleven days, instead of ten.

There were seven days in the Shire week. The first day of the week was called Sterday and the last day of the week was called Highday. The Mid-year's Day and, when present, Overlithe had no weekday assignments. This arrangement was used because it caused every day to have the same weekday designation from year to year (instead of changing as in the Gregorian calendar

Lithe fell between Forelithe, the sixth month of the year, and Afterlithe, the seventh month. In most years there were three Lithedays: 1 Lithe, Midyear's Day, and 2 Lithe. In Leap-years there was a fourth Litheday called Overlithe between Midyear's Day and 2 Lithe. Midyear's Day and Overlithe were not assigned any weekday, while 1 Lithe always fell on a Friday and 2 Lithe was a Saturday. Lithe and the Midwinter holiday called Yule were the two major holidays in the Shire. Lithe was a time of great feasting and merriment. During Lithe, the Free Fair was held on the White Downs, where Hobbit

s gathered to celebrate and to buy and sell goods. Every seven years at the Free Fair during Lithe, an election was held for the office of Mayor of Michel Delving. In the years that Overlithe occurred, it was a day of special celebration. Overlithe fell during the Great Year of Plenty in 3020 after the War of the Ring, and it was the merriest holiday in the history of the Shire.

The word lithe is from the Old English líða. This may have been the name for Midsummer, while ærra Líða and æftera Líða were used for the months June and July. The word lithe means "mild, balmy" in relation to the weather.

Yule was one of the two chief holidays in the Shire—the other being the midsummer holiday called Lithe. The Yule celebrations lasted six days in total, including two days before and two days after the Yuledays. This six-day period was called Yuletide. It was a time of feasting and merriment.
