20 19. 1.26 calendar
The Gregorian calendar we are using now is the Gregorian calendar that has been used since 1582. Gregorian calendar shows 12 months, and the number of days in each month varies from 28 days, 30 days and 3 1 day. Every year divisible by 4 is a leap year. Except the year divisible by 100, all the trans-century years divisible by 400 are leap years, so-called "a leap in one hundred years, a leap in four hundred years". For example, 1700, 1800 and 1900 are not leap years, but 2000 is a leap year.
There are 365 days in a year. Every year 1, 3, 5, 7, 8, 10,1February is a big month, and every month is 3 1 day; April, June and September 165438+ 10 are abortion, with 30 days per month; February in leap year is 29 days, and February in normal year is 28 days.

What is the perpetual calendar for?
That is, it can automatically identify the big month (3 1 day) and the small month (30 days) and February (28 days) in a year, and then automatically identify leap years every four years. February is 28 days in a normal year and 29 days in a leap year. A functional watch that jumps every four years. Such a magical intelligent operation is not completed by electronic programs, but by mechanical operations, which is even more amazing.
A mechanical watch with perpetual calendar function, if the watch has been running normally without stopping, it will not need to be adjusted for at least 100 years? -Of course, most cousins don't live that long?
One of the oldest perpetual calendars in history, Patek Philippe's 3940. 6 o'clock indicates the date and moon phase, 9 o'clock indicates the week (with 24-hour indication at the same time), and 3 o'clock indicates the month and leap year.

1889, Patek Philippe applied for a patent for perpetual calendar technology, which was the last important technology that influenced the watch industry when Adrian Feili, one of the founders of Patek Philippe, was alive (he invented keyless winding in 1844).
1925, one of the perpetual watches in history. It is also one of Patek Philippe's perpetual calendar watches (No.97975). Since then, the perpetual calendar function has been the most important and complicated function of Patek Philippe watches.

1985, Patek Philippe 3940, which influenced the design of modern perpetual calendar watches, came out, equipped with the famous Caliber 324SQ automatic perpetual calendar movement. Patek Philippe 3940 is one of the oldest perpetual calendars in history, and it was not replaced until May, 2006140. Patek Philippe's favorite watch of the third generation Stearns family is the perpetual calendar. The longest worn watch is 3940, which has been worn for more than 30 years and is an indispensable part of Mr. Phillips' life.
1985, the Leonardo da Vinci calendar (with timing function) came out. This is one of the mass-produced watches with perpetual calendar function, and it is also one of the perpetual calendar watches with year display window in history.

1762, one of the perpetual calendar pocket watches in the existing history, was created by Thomas Mudge, a British watchmaker.

What's interesting about the perpetual calendar?
As mentioned earlier, the magical timing function brought by magical mechanical skills. For people who love watches, especially those technical men and perpetual calendar fans, the last day of February is their own holiday every year? -Look at the date of February, and jump directly from February 28th to March 1 (general calendar watches, including February, have to manually adjust the calendar every month, and 30-day abortion is also manually adjusted, because the date dial indicates 3 1 day). Every leap year of 4 years is a big holiday! ? Look at the date-28th, and jump out of February 29th of leap year. Then watch the 29th in the middle of the night and jump directly to March 1! Is this hobby simple and silly?
The perpetual calendar has complex functions and precise mechanical operation. Most perpetual calendar watches are difficult to adjust after they stop. Therefore, most people who have perpetual calendar watches will have a watch turner, so that they can wind up their watches when they are not in use, which can not only ensure the normal operation of perpetual calendar watches, but also avoid the trouble of adjusting time. Of course, mechanical watches also have errors. Every once in a while, you have to adjust your watch and the error. In this way, your perpetual calendar watch can really run accurately for "10,000 years". Wear it at any time, and your watch will accurately display the time information of today's time, date, week, month and month.
People who like perpetual calendars should also distinguish between "full calendar", "almanac" and perpetual calendars. Although the time information displayed on the dial is almost the same, they are quite different from perpetual calendars, especially full calendars. The full calendar only displays the date, week and month, and cannot automatically distinguish between big month, small month, February and leap year, so it should be manually adjusted at least five times a year (2, 4, 6, 9, 1 1 month). Calendar is far from the perpetual calendar that automatically recognizes February and leap years, so it needs to be manually adjusted 1 time a year. There is no need to manually adjust the perpetual calendar within 100 years. The brand's annual calendar is sometimes less than half the price of a perpetual calendar.
The calendar circle of the simplest calendar is 3 1 day. No matter what month you are, the default is to jump from 3 1 to next month 1. Therefore, February 28th, 30th of abortion in normal year and February 29th of leap year must be manually adjusted to March 1. The perpetual calendar watch realizes intelligent automatic jump through complex mechanical operation.
