"Ganzhi Clock" provides real-time "Ganzhi" message and "pointer" clock, and can specify a "time zone" or "location" to display the current time in that time zone. The functions are as follows:

》Perpetual calendar calculation core:
●According to the currently set time zone, calculate with ephemeris: precise transfer time of the 24 solar terms (moon column), new moon time (new moon determines the size of the lunar month), and intercalation without middle air.
●Note: Therefore, the size, month and column of the lunar calendar in each time zone will be slightly different. If you compare the perpetual calendar with 120 degrees east longitude on the market, there will be a slight difference. This is not a mistake.

》Two clock styles are provided:
●Ordinary clock: when the clock face shows 1~12 in large letters, 13~23 in small letters, the inner circle shows twelve earthly branches for reference.
●Twelve o'clock clock: The clock face displays twelve o'clock, which is convenient for viewing the current time. Each pointer represents the following:
　●The "hour hand" makes a full circle in exactly one day, there are twelve hours, and one hour is two hours.
　●The "minute hand" makes a round of exactly one hour, two hours, 120 minutes, and 120 graduations.
　●The "second hand" makes one revolution for one minute, that is, 60 seconds, which is the same as a normal clock.
●You can click the clock to switch the above two clock styles.

》Time zone location:
●Time zone setting: Provide the global time zone name, which can be searched and set.
●Place setting: Enter the place name or address, and the time zone and place latitude and longitude can be automatically set through the network (Internet connection is required).

》Date display:
●Display the current "Lunar Calendar" and "Gregorian Calendar" date comparison, real-time "digital time" and "week".
●Click "Lunar Calendar/Gregorian Calendar" in the upper right corner to enter the specified date (after the specified date, you can click the clock to display the current time).
●Display the current "time zone".
●Display the current "location" and latitude and longitude (if a true sun is set, a prompt will be displayed).
●Note: If both the time zone and location are displayed, it means the current location time. If only the time zone is displayed, it means only the time zone time.

》Preferences:
●Four-column sequence: Set the four-column display sequence.
●Year column handover: Set the handover point of the year column solar terms.
●Night time: Provide night time setting.
●Southern Hemisphere Moon Branch: Set to hedge or not to the northern hemisphere moon branch.
●Four-pillar solar terms: Set whether the four-pillars should be based on solar terms.
●Using time: Set the time of use time zone or location time.
●True solar time: Set whether the four pillars should be corrected for true solar time.
●Language area: switch the interface language at any time, providing traditional Chinese and simplified Chinese.
●Interface font: Provide font size adjustment.
●Screen lock: It can be used for a long time if it is not locked, and the screen will not turn off.
