Make up for the time difference in a regular way, which is somewhat similar to a watch. Every four years, add a day to the Gregorian (the current Gregorian calendar), keeping the number of days set by the artificial calendar consistent with the actual revolution of the Earth. The actual time the earth orbits the sun is 365.242189 days (or 365 days 5:48:45), whereas the Gregorian calendar is only 365 days a year, with an annual difference of nearly 6 hours, so if not every four years On the following day (ie February 29th), our calendar will be delayed by nearly 6 days in just 25 years. Reliable and practical life partner To accurately measure the date and week of the wrist, many brands have introduced calendar watches that display dates, weeks and months. The specific function depends on whether it is an annual calendar or a perpetual calendar watch. In any case, in today's busy society, calendar watches have become a reliable and practical companion. Basically, the calendar watch traces the time information on the wrist month by month, showing the date, week and month, as well as the 30-day and 31-day months. However, this type of watch usually needs to be manually adjusted at the end of February (28 or 29) to achieve a date reset.
