Today it is called “Le Day”, and it is also called “Perpetual Calendar!” .
First, take a quick look at the perpetual calendar… The perpetual calendar is an accurate description of the Gregorian calendar. It is unique in its ability to automatically calculate the correction for the year. Every four years, the table will automatically consider additional dates in the annual calendar starting on February 29. Then, it will automatically transition to March 1 after February 29. This seems to be a small difference from the annual calendar, but there is a big difference in the level of tabulation required. The calendar will be corrected until March 1, 2100, ignoring the year. However, some perpetual calendars are designed to correct themselves when ignoring the year, which means that adjustments are not required until 2400.
The history of the perpetual calendar
An English watchmaker named Thomas Mudge invented several important watch parts, including lever escapement, equation of time device, minute repeater and important perpetual calendar. Mudge was born in 1715 and died in London in November 1794. He began his apprenticeship in watchmaking at the age of 15 under the guidance of George Graham. In 1728, he finally qualified to become a watchmaker and was employed by many retailers. When making complex equation watches for John Ellicott FRS, Thomas was found to be the actual manufacturer of the watch, which made him directly entrusted by Ferdinand VI of Spain. He made at least five watches for Ferdinand VI, including a watch that could repeat hours, quarter hours and minutes – three minutes per minute. Around 1755, Mudge created an independent lever escapement-this will be one of his most famous inventions and is considered to be one of the biggest improvements applied to watches. The oldest known perpetual calendar can be traced back to the pocket watch of 1762, which is stored in the British Museum.
Patek Philippe and Perpetual Calendar
In 1889, Patek Philippe officially applied for a patent for a perpetual calendar device for the first time. This is specially designed for pocket watches, which can be instantly jumped in the day, date, month and moon phase. This Patek Philippe movement combines a wheel, a heart-shaped part and multiple levers. These levers, levers and levers act simultaneously to rotate the star wheel. Patek Philippe produced the first wristwatch with a perpetual calendar in 1925. The movement uses a pendant movement. An enthusiastic American watch collector Thomas Emery commissioned Patek Philippe to make this perpetual calendar. Patek Philippe finally regained this history for display in the Geneva Museum. Today, Patek Philippe is known for its amazing complications.
