Ren can help map how information travels through a large collaboration.

Native app reference
The original examples describe Synastry’s date-only native year reader. This web guide does not calculate a placement or a Four Pillars chart.
Keep the calendar convention in view
The website offers these educational readings. Synastry’s native year reader uses a civil date and Lunar New Year; it is separate from a full Four Pillars or BaZi chart. Begin with the convention before comparing year labels.
