Calculated with care
• Month pillars change at the exact moment of each solar term, computed from astronomical data.
• Korean local time, historical time zones and daylight saving time are corrected automatically.
• Choose how the Ja hour, luck pillar start age and other differences between schools are handled. The app shows how every value is calculated.

Private by design
• No account and no server. Charts are calculated and stored only on your phone.
• Works offline. Ads need a connection, but every feature works without them.

Free, with light ads
A small banner appears on some screens, never on the chart itself. Watch one short video to hide banners for 24 hours.

Saju is a traditional practice for entertainment and reflection. Readings are not scientific predictions, so please don't base important decisions about health, money or law on them.
