Frustrated with saju calendar apps?
"I can't tell whose chart is whose or where I saw it" · "I wish there were folders"
"I'd love to add notes to saved people" · "what happened to them, and when"
"The hour pillar is different from what I knew" · "It doesn't say which day the monthly pillar changes"

Frequently asked questions
Why is my hour pillar different from other apps?
Calendars differ in longitude correction (about −30 minutes for Korea), historical daylight saving time and whether they use the late-night rat hour. Near an hour boundary these change the result. Myeongsik Note shows which basis it used above the chart and lets you change it in settings.
On which day does the monthly pillar change?
Month pillars change at each solar term, not on the lunar 1st. Myeongsik Note shows the start date next to every monthly pillar.
Can I add notes to people I've saved?
Yes. Every person has notes, and you can log events like "2024.5 changed jobs" to read next to their luck cycles.
Can I sort charts into groups like family or clients?
Yes. Save charts into groups and browse them by group from the home screen.
The terms are hard — is there an explanation?
Tap any ten-god, life-stage or star chip for a one-line explanation.
How do I move my data to a new phone?
Back up to a single file in settings and import it on the new phone. There is no account or server; data stays on your device.
Does it tell my fortune?
Myeongsik Note calculates and displays charts according to the traditional calendar. Four Pillars content is traditional culture, provided for reference and study — it does not predict or guarantee anything.
