Sun and Moon Astronomical Data for Programming

Before looking for our data format, we want to compare the Sun and Moon data with the book of The American Ephemeris for the 21st Century 2001 to 2050 at midnight by Neil F. Michelsen, a calendar bible for western astrology. The difference of two astronomical data should be within 1 minute, because some data without seconds. You will have strong confidence using our data.

The Sun and Moon Astronomical raw data is calculated by Universal Time (UT), a.k.a. Greenwich Mean Time (GMT). click for detail. We provide Visual Basic (VB) Programs with source codes to convert the data from UT to different time zones.

The following are sample data for your reference.

Moon

Full Moon Data is good for the application to find the Easter related holiday.

Sun

Mix Sun and New Moon Data

The VB program combines Sun and Moon Data in the Chinese Astronomical and Civil Calendar sequences from Different time zones.

Lunar Months

The VB program calculates the Chinese Astronomical and Civil Lunar Months from Different time zones.

Lunar Leap Months

The VB program lists Chinese Astronomical and Civil Lunar Leap Months with Double-Center-Point months from Different time zones. It also indicates the Fake Leap Months.

Another VB program compares the discrepancy about the assignment of Lunar Leap Months from different time zones.
