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
- Updated the precession model using the IAU2000 standard.
- Verified HD193496 star coordinates matching Stellarium data (2024 to 16,317 BC).
- Noted discrepancies in Jupiter’s ancient data.
OldSky Version 1.5
- Added support for the 27 lunar mansions.
- Integrated drawing elements from @LD_daofeichang’s ancient astronomical charts.
OldSky Version 1.51
- Refined and corrected the precise division of the 12 Ci (zones) based on @LD_daofeichang’s chart.
OldSky Version 1.52
- Fixed display issues for the 12 Ci and 27 lunar mansions experienced by some users.
OldSky Version 1.6
- Added precise correspondence between the 64 hexagrams and the 24 solar terms.
- Improved background display adjustments.
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.

- 与 Stellarium 校对了 HD193496 恒星坐标,从公元 2024 年至公元前 16317 年完全一致。
- 木星古代数据存在差异。
OldSky 版本 1.5
- 添加了 27 宿支持。
- 集成了 @LD_daofeichang 的古天文图表元素。
OldSky 版本 1.51
- 根据 @LD_daofeichang 的图表,进一步精确矫正了 12 次的分区位置。
OldSky 版本 1.52
- 修复了一些用户下载软件后,12 次与 27 宿显示不正常的问题。
OldSky 版本 1.6
- 增加了 64 卦与 24 节气的精确对应。
- 改进了显示背景的调整功能。
OldSky 版本 2.0
主要功能:
- 集成了 DE441 星表: 提供可追溯至 13000 年前的精确行星位置计算。
- 开普勒行星轨道计算: 用于星表有效期之外的行星位置外推计算,并通过行星周期对算法进行验证。
- 最新的岁差章动模型: 已与 Stellarium 进行了验证,确保计算精度。
- 集成 VSOP87 星表: 星表已包含在软件中,但暂未使用。
由于 DE441 星表数据体积较大(约 2.5 GB),上传文件的体积相对较大。
