You can download a beautiful lunar almanac and still not have a BaZi personal calendar. The first is a shared day planner rooted in folk timing (通胜). The second is a personal timeline built from your birth year, month, day, and hour pillars. Confusing them is how beginners think the yellow calendar “knows” their private luck.
This page bridges Yi / Ji basics and four pillars. Mallria draws public almanac data and personal chart logic from Lushn, our calendar and chart engine partner.
Side-by-side
| Lunar almanac (L1) | BaZi personal calendar (L3) | |
|---|---|---|
| Input | Today’s date (maybe location) | Birth date + time (+ place for precision) |
| Output | Day stem-branch, Yi/Ji activities, stars | Flow year / month / day vs your chart |
| Same for everyone? | Yes on Yi/Ji for that civil day | No |
| Best for | Holidays, folk timing, cultural literacy | Personal color days, study, match flow depth |
| Wearable tie-in | “Today’s day element” color play | Day-master palette, stored profile tags |
What the almanac layer gives you
On any given day the almanac answers: What is today’s day pillar? What activities are traditionally marked Yi or Ji? Millions of people see the same list. That is useful for:
- Lunar festival dates and etiquette gifts.
- Conversation starters (“apparently today is a travel Yi day”).
- Learning heavenly stems and earthly branches on a wall calendar.
It does not know your hour pillar or your Day Master.
What changes when you add four pillars
Once match flow (or chart software) computes your pillars, the system can overlay:
- Flow years (流年): how the current year pillar interacts with yours.
- Flow months / days: finer slices for students and enthusiasts.
- Personalized wearable tags: which element colors echo your chart, not just the public day.
A day with two kinds of information (example)
-
Morning
Check the almanac
App says “Ji: major contracts.” You note it, maybe delay a signing. Folk habit.
-
Afternoon
Open match flow
With birth time saved, your profile highlights Water tones this month for your chart. Different information.
-
Gift
Pick colors
You buy a navy cord bracelet (Water color story) because it matches the personal tag, not because the almanac said so.
Planned on Mallria
- Public almanac page: L1, no login.
- Saved BaZi calendar: L3, requires stored pillars (Lushn-backed).
Until those ship, use the sister guides above plus match flow for personalization.
FAQ
- Is the almanac “wrong” if my BaZi flow day disagrees?
- They answer different questions, not right vs wrong. Almanac is public L1; flow day is personal L3.
- Do I need Lushn / Mallria for a paper calendar?
- No. Paper is pure L1. Personal layers need software and your birth data.
- How does this relate to stems and branches?
- Both almanac day pillars and birth pillars use the same stem-branch vocabulary. The difference is “today only” vs “your four time coordinates.”
