Chinese Calendrics Software 7. Date Conversion Chinese Calendrics converts dates in the following calendars:
Conversion of a date in one calendar to dates in all the other calendars may be made by entering a date in any of the calendars into the 'Enter date' box and clicking on 'Convert'. You can specify a time (GMT, Chinese or local) in the 'Time' box. If no time is specified then 12:00 (in whatever timezone is shown) is assumed.
- Common Era (Gregorian)
- Julian Calendar
- Chinese Lunar Calendar
- Chinese Solar Calendar
- Julian day numbers (astronomical and various chronological)
Common Era and Julian dates (dates in the Julian Calendar) are displayed (and must be entered) in ISO 8601 format, that is, 'year-month-day'.
Note that (as mentioned in Section 3) the year-numbering system employed in date entry is the astronomical year-numbering system, in which years B.C. are represented by negative integers: 1 BC = 0 CE, 2 BC = -1 CE, 3 BC = -2 CE, and so on. So the 31st of December 22 B.C. is -21-12-31 CE. For a fuller explanation see Astronomical Year Numbering.
Chinese solar and lunar dates must be entered as 'cycle-position-solarterm-day CHS' and 'cycle-position-month[*]-day CHL' respectively.
If you know the element-animal denoting the year in the Chinese Lunar Calendar, but you don't know the position number, then you can enter 'cycle-?-month-day' and specify the element and animal using the drop-down lists. The example at right shows how to specify the 15th day of the 8th month in the metal-dragon year of cycle 77. After clicking on 'Convert' the date of 77-17-08-15 CHL appears. The drop-down element and animal lists are active only after a CHL date has been entered (press the 'Enter' key or click on the 'Convert' button) with '?' in place of a position number.
Clicking on a date displayed on-screen (in yellow) will copy it to the 'Date' box, and the time will be copied to the 'Time' box. You can then modify that date and time and click on 'Convert' to obtain corresponding dates in the other calendars.
Clicking on a date displayed on-screen (in yellow), or the label to the left of it, will copy the entire date and time to the clipboard, from which it can be pasted into another document. This also works for the values of 'Phase of Moon' and 'Age of Moon'.
