- For
- Shan learners and readers of calendar history
- Worth noticing
- The page labels its orbital animation as a teaching model, not an ephemeris, and contrasts Chinese, Burmese, and Tai leap-month rules.
Field notes
The lesson sequence links tropical year, synodic month, solar terms, leap-month rules, and the Tai 60-year cycle. Interactive controls let visitors rotate and zoom a Sun–Earth–Moon model, inspect lunar illumination, and compare calendar modes; the page explicitly says the model is illustrative rather than an ephemeris. Navigation also lists a Julian converter and Tai Year Archive.
