OldSky Version 1.1

OldSky Version 1.2

OldSky Version 1.3

  • Introduced a preliminary lunar calendar function with some inaccuracies for ancient dates.
  • Aligned the lunar calendar Winter Solstice with the corresponding year.
  • Applied higher-precision models for Sun, Moon, Mars, and Jupiter orbits.
  • Enhanced the accuracy of the 28 lunar mansions using an improved precession model.
  • Added automatic local-to-UTC time conversion.

OldSky Version 1.4

OldSky Version 1.5

OldSky Version 1.51

OldSky Version 1.52

OldSky Version 1.6

OldSky Version 2.0

Features:

  • Integrated DE441 Ephemeris: Provides accurate planetary position calculations dating back to 13,000 years ago.
  • Keplerian Orbital Calculations: Enables extrapolation of planetary positions beyond the ephemeris validity period, verified using planetary orbital periods.
  • State-of-the-Art Precession and Nutation Models: Validated against Stellarium for accuracy.
  • VSOP87 Ephemeris: Included in the software but not utilized.

Due to the substantial size of the DE441 ephemeris data (approximately 2.5 GB), the uploaded file is relatively large.
