In BaZi tradition, a flow day (流日) is today’s day pillar read against your four birth pillars — apps use that to flag daily element emphasis. That is separate from the public almanac Yi / Ji everyone shares. This page explains flow year, month, and day in plain English and how Mallria turns that into wearable color suggestions.
Still confused about almanac vs personal calendar? Start with lunar almanac vs BaZi calendar. Need pillar vocabulary first? Read what is BaZi? Chart math comes from Lushn behind Mallria’s match flow.
Three time slices: 流年 · 流月 · 流日
| Chinese term | Plain name | How fast it moves | Wearable question it raises |
|---|---|---|---|
| 流年 | Flow year | Changes at Lunar New Year boundary (apps vary) | “This year’s accent color on outerwear?” |
| 流月 | Flow month | Changes each lunar month | “Scarf or bag hue for this month?” |
| 流日 | Flow day | Changes every civil day (new day pillar) | “Subtle tone for today’s commute?” |
Your Day Master (日主), the stem of your birth day pillar, is the anchor. Flow pillars are moving weather against that anchor. Software summarizes the interaction as element emphasis (Wood, Fire, Earth, Metal, Water) — palette narrative. For the slower ten-year luck pillar (大运) timeline, see luck pillar explained.
L1 almanac day vs L3 flow day (do not merge them)
| Almanac day pillar (L1) | Personal flow overlay (L3) | |
|---|---|---|
| Same for everyone? | Yes, today’s 日干支 is shared | No, depends on your four pillars |
| Typical output | Yi / Ji activity list, folk stars | Element tags, chart-friendly color notes |
| Wearable use | Optional “today’s day element” color play | Profile-aware palette for you |
| Needs birth time? | No | Yes (hour pillar for full chart) |
Example: the almanac might mark a day as Yi for travel while your flow-day tag leans Metal-neutral gray. Both can be true. They answer different questions.
What match flow actually computes
When you enter birth date, time, and (optionally) place in match flow, the pipeline roughly does:
-
1
Build four pillars
Year, month, day, hour stems and branches.
-
2
Derive phase weights
Which of Wood / Fire / Earth / Metal / Water read loud in your profile (Day Master + supporting stems).
-
3
Overlay flow pillars
Current year, month, and day branches against your chart.
-
4
Emit wearable tags
Metal-forward silver, water-dark navy, earth camel, etc., as symbolic color emphasis.
From flow tag to something you can wear
Think three layers you can mix on a birthday gift card:
| Layer | Source | Wearable example |
|---|---|---|
| Day Master baseline | Your birth day stem | Default palette year-round, see five element colors |
| Flow month accent | Current 流月 vs chart | Scarf or tote in the emphasized phase this month |
| Flow day whisper | Today’s 流日 | Socks, cord, or clip: small surface, easy swap |
Practical rule: month-level accents beat day-level shopping sprees. Nobody needs seven new bracelets because seven flow days favored Fire.
Phase → color cheat sheet (symbolism only)
- Wood: green, botanical prints, wood-bead cords
- Fire: burgundy, warm red wraps, see home vs wear colors
- Earth: camel, ochre, brown leather tones
- Metal: silver-gray, hematite clips, clean stripes
- Water: navy, ink blue, dark merino
Four scenarios
- Gift buyer: only know her birthday
- Stay on sun-sign or year-animal gifts. Do not cite her flow day; you lack the hour pillar. Use birthday bundles or five element colors instead.
- You have date + time from family text
- Run match flow. If Water jumps in the bar chart, a navy tote + dark merino scarf is a coherent story. Card line: “Your chart leans depth blue this season, not because the almanac said so.”
- Daily enthusiast checking flow 流日
- Use flow day as a small accent: socks, cord, coin charm on a bag ring. Pair with L1 almanac literacy, not replacement.
- Comparing Western five-planet mode
- Western mode scores elements from planets; Eastern mode from stems and branches. The match flow lets you pick a tradition; neither mode is “truer” than the other. Read how birth time changes your match.
Try it: match flow checklist
- Skim five elements basics so output colors make sense.
- Gather date + time (place if birth was far from hospital timezone).
- Open match flow → choose Eastern / BaZi path.
- Note which element leads: that is your wearable color reference for the day.
- Shop sister guides for SKU ideas (scarves, bags, cords); put the color narrative on the card.
- Planned: saved BaZi calendar on Mallria (L3), revisit monthly, not hourly shopping.
FAQ
- Is today’s flow day the same as today’s almanac day pillar?
- The underlying day stem-branch is shared. The personal tag differs because software weighs it against your chart.
- Do I need a new wearable every flow day?
- No. Month-level accents + a stable Day Master baseline are enough for gift stories.
- Where is the personal calendar product?
- On the roadmap with Lushn-backed L3 pages. Until launch, match flow plus these guides are the bridge.
