Field notes
The calculator separates year changes at Risshun and month changes at seasonal boundaries rather than using January 1 or the first day of each month. Its direction model divides the compass into 30-degree cardinal sectors and 60-degree diagonal sectors, then uses spherical trigonometry from true north to calculate bearings. A separate relocation view lays out three years of monthly options, while the site says birth-date data stays on the device.
