A PUBLIC EXAMPLE · NO PERSONAL INPUT

One birthday. A chart. A new set each week.

New to Saju? It is the Korean Four Pillars tradition: a birth year, month, day and hour are represented by four pairs of calendar symbols. Our weekly numbers are a separate, site-designed layer. Try this example to see the difference before sharing any birth details.

Example only: 1 January 2000, 12:00 local civil time. These are fixed historical weeks, not your current reading. No birthplace or timezone correction is applied.

Year: 己卯
Month: 丙子
Day: 戊午
Hour: 戊午

01 · Calendar calculation

The first symbol of the Day pair is 戊: Yang Earth, the Day Master. It stays the same when you switch these example weeks; the birth chart is not recalculated from the current date.

With the hour unknown, the Hour Pillar is omitted. For this example, the Day Master remains Earth, so its weekly numbers stay the same. This does not hold for every boundary case: unknown times near a solar-term or day boundary need independent checking.

02 · Our weekly number rule

The generator combines the birthday, Day Master element and Sunday week-start date in Korea. Switching A to B changes only the week key, not the birth chart. It shuffles 1–45 and takes six distinct values. Reopening the same example does not reroll it; different inputs can coincide.

03 · A reflection you choose

For this Earth-themed example, use the image of steady ground as a writing prompt: What small routine helped me feel settled this week? Choose one action, then check what actually happened. This is our editorial exercise, not a conclusion calculated from the symbols or numbers.

Give your lucky numbers a small ritual

Your numbers are a playful weekly keepsake, not a forecast. Choose one activity below. These are our editorial interpretations of the Five Elements—not a diagnosis or a claim about who you are. You can choose any element, regardless of your chart.

Wood · begin

Sketch one small idea you have been postponing. For example, write three possible openings for a personal project; pick one to try.

What did starting teach me that planning did not?

Fire · express

Share one specific appreciation with someone, without expecting a reply. For example, name a small action that made your day easier.

Did I express what I actually meant?

Earth · make space

Reset one small surface or folder. For example, clear your desk corner and decide what belongs there; leave the rest for another day.

What became easier after I made a little room?

Metal · refine

Finish or simplify one small unfinished item. For example, edit a draft down to its three essential points instead of adding more.

What could I remove without losing what matters?

Water · notice

Pause and observe something familiar for five minutes. For example, notice a route, a piece of music or a conversation without trying to explain it.

What did I notice when I stopped rushing to a conclusion?

Use your Gregorian birth date and recorded local clock hour. This tool does not convert birthplace time zones, historical daylight saving or longitude. Near midnight or a solar-term boundary, the chart may differ from a location-corrected reading. Unsure of the hour? Leave it blank.

The six-number range is not a universal lottery format. This tool does not model a lottery draw, recommend a ticket or give one set better odds than another.

This preview uses only the public example above. It does not call the AI reading service or collect your birthday.

Your chart and numbers, one weekly reading

Enter your birthday to receive your Saju chart and weekly lucky numbers together. Enjoy a personalized experience inspired by the cosmos and Five Elements. The number-generation rules are explained below.

For entertainment. There is no evidence that Saju or cosmic energy predicts lottery wins or improves the odds.

How are these numbers created?

Your birth date, Day Master element and the week-start date in Korea seed six distinct numbers from 1–45. The same inputs in the same week give the same numbers. Different inputs can sometimes produce the same result.

A new week starts Sunday at 00:00 Korea Standard Time. The week key changes and numbers are generated again. Number generation runs on your device, separately from the AI reading. Enjoy the dated set as a personal symbol for the week.

This is a site-designed pseudorandom rule, not a traditional Saju formula for winning. The element is a personalization input, not an accuracy or luck score. Although the range matches Lotto 6/45, these numbers have no connection to its draw. We do not encourage purchases or betting.

How is my chart calculated? — Explore an example and a quick quiz

Reading lab: eight characters, one transparent calculation

This is a reproducible example from our own calendar engine, not a real person's case study or an independent accuracy certificate. Input: Gregorian 2000-01-01, 12:00, entered-clock convention, no location adjustment.

己卯 · 丙子 · 戊午 · 戊午

1 · Find the Day Master

Read the pairs in Year, Month, Day, Hour order: 己卯 · 丙子 · 戊午 · 戊午. The first character of the third pair is 戊. That is the Day Master; its primary element is Earth. It is not whichever element has the largest percentage.

2 · Count symbols, not personal qualities

The stems 己, 丙, 戊, 戊 contribute Earth, Fire, Earth, Earth. The branches 卯, 子, 午, 午 contribute Wood, Water, Fire, Fire. Totals: Wood 1, Fire 3, Earth 3, Metal 0, Water 1. Hidden stems and seasonal strength are not included. Metal 0 means no visible symbol received that label—not a deficiency in the person.

3 · Reconcile the displayed percentages

Divide each count by eight. The exact values are 12.5%, 37.5%, 37.5%, 0%, 12.5%. To show whole numbers summing to 100, we floor the values, then distribute the remaining points by fractional remainder, count, and the fixed Wood–Fire–Earth–Metal–Water order. The displayed result is 12%, 38%, 38%, 0%, 12%. A one-point rounding difference is not a meaningful difference in a person.

4 · Remove the hour and recount

Choose Unknown rather than guessing noon as your birth hour. The Hour pair is omitted. The six remaining symbols give counts 1, 2, 2, 0, 1 and displayed percentages 17%, 33%, 33%, 0%, 17%. The Day Master is still 戊 in this example. Noon is used provisionally for the other pillars, so this comparison is not a guarantee on solar-term boundary dates.

Check your understanding: why does this example show Metal 0%?

The visible-symbol count contains no Metal label.

Exactly. It describes this counting method and these inputs only. Hidden-stem methods may count differently; no health, personality, or outcome follows from this zero.
