Chinese Almanac Today & Auspicious Date Checker 择日

Most date-selection tools hand you a wall of Chinese jargon or a generic list of "lucky days." This one does neither. Tell it the date you're considering — or browse a whole month — and it explains, in plain English, why a day is good or bad for your event: the officer of the day, clash days, special almanac days, and whether the date collides with your own chart, not just your zodiac animal. Built for Singapore: local time, weekends, public holidays and the Hungry Ghost month are all in the calendar.

One person's chart is checked free. Choosing for a couple or a whole family is a different job — more on that below the tool.

Two questions, one almanac. Above: what today is — its day pillar, its officer, the zodiac sign it clashes, and what that suits. Below: whether a specific date works for a wedding, a move, a renovation or an opening, checked against your own chart rather than a generic lucky-day list. Singapore time, public holidays and the Hungry Ghost month are built in.

Built for everyone to use, and computed exactly from the classical rules. But a result is not a reading — charts are interpreted as a whole, and that craft belongs with a practitioner. Treat this as the map, not the verdict.

What is 择日 (date selection)?

择日 — literally "selecting the day" — is the Chinese practice of matching an event to a date whose energies support it. It sits behind every Tong Shu (通书) almanac ever printed: those 宜/忌 ("suitable / avoid") lists your grandmother consulted before fixing a wedding banquet are the output of a small number of deterministic rules applied to the day's stems and branches. The rules aren't mystical secrets; they're a calendar system. What most people lack isn't access to the rules — it's a translation. That's what this tool is: the classical almanac layer, computed exactly, then explained.

‍ ‍

The engine: the Twelve Day Officers 建除十二神

The backbone of every Tong Shu is a twelve-day cycle called the Twelve Day Officers (建除十二神). Each day is assigned one officer based on how the day's branch relates to the month's branch, and each officer favours some activities and warns against others:

  • 建 Establish — initiating energy; good for setting out, poor for groundbreaking.

  • 除 Remove — clearing away the old; good for decluttering and ending habits, not for celebrations.

  • 满 Full — abundance; a classic day for weddings and openings.

  • 平 Level — an even, ordinary day.

  • 定 Settle — the signing day: agreements, engagements, confirmations.

  • 执 Hold — grasping; good for contracts and hiring, poor for moving.

  • 破 Break — the month's clash day; unfavourable for anything celebratory.

  • 危 Danger — a precarious day; caution for major undertakings.

  • 成 Succeed — completion; among the best days for almost everything.

  • 收 Receive — gathering in; good for collecting and receiving payment.

  • 开 Open — opening up; launches, moving in, starting work.

  • 闭 Close — sealing; suited to closings and endings, not weddings or moves.

‍ ‍

On the day a solar term begins, the officer repeats — which is why the cycle stays locked to the solar months. The tool computes this astronomically for Singapore time, so the officer shown here matches the printed almanac.

‍ ‍

What else the verdict weighs

Beyond the officer of the day, each verdict checks:

‍ ‍

Clash days. A day whose branch directly clashes the month branch (月破) or the year branch (岁破) carries the almanac's heaviest warnings. The day's clash animal (日冲生肖) is always shown — if the day clashes your zodiac sign, everyone from your florist to your mother-in-law will mention it, so you may as well know first.

‍ ‍

Special days. A handful of named days move the needle: the Heavenly Pardon 天赦 (one of the best days of each season for fresh starts and settlements), the Four Abandonments 四废 (the day's element dead against the season), and the Ten Great Depletions 十恶大败 (the "empty granary" days).

‍ ‍

Your own chart — the personal layer. This is what generic almanac sites can't do. Enter your birth date and the tool checks the day's branch against both your year branch and your day branch for clashes 冲, punishments 刑 and harms 害 — reported separately, so you can see which part of your chart is hit. A date that's perfectly auspicious in the almanac can still clash your day branch — the spouse palace — which matters rather a lot if the event is your wedding. The tool also notes whether the day's element feeds or drains your Day Master, weighted lightly and labelled honestly as an approximation.

‍ ‍

The Singapore layer. The calendar marks weekends and every gazetted public holiday for 2026 and 2027 (per the Ministry of Manpower), because a perfect Tuesday is useless for a wedding banquet. Event types are the ones people here actually choose dates for: wedding banquet, Guo Da Li 过大礼, moving house, moving altar 安神位, renovation start, business opening, contract signing, fengshui audit and travel.

‍ ‍

Days Master Yuan does not conduct fengshui audits

Fengshui has its own calendar discipline, and part of engaging a practitioner seriously is knowing that some days are simply not offered — by rule, not by mood. Select "Fengshui audit 风水勘察" in the tool and it applies Master Yuan's own calendar: no audits on the thirteen 杨公忌日 (the Yang Gong taboo days of the lunar calendar), none on the eight 四绝 and 四离 days (the eves of the season gates — the day before each solstice, equinox, and season start, when one season's qi is exhausted and the next has not yet arrived), and no on-site audits during the lunar seventh month. The tool computes all three astronomically, so before you WhatsApp to book an audit, you can already see which days are off the table — and why.

‍ ‍

About the Hungry Ghost month

The lunar 7th month is the single biggest folk consideration in Singapore date-picking, and most international tools ignore it entirely. This tool computes it astronomically (the lunar month containing the solar term 处暑) and flags every affected day. Deliberately, it's an amber flag, not a veto: the traditional avoidance applies to weddings and moves in Chinese custom, and if that isn't part of your beliefs, the almanac assessment stands on its own. You'll see the note; you decide what it means for you.

‍ ‍

How to use this for a wedding date

Start in Browse a month with your banquet window, tick "weekends & holidays only" in the finder, and let it list the next five auspicious dates. Then add your birth date and watch the map change — this is the point of the personal layer. A classical rule worth knowing: wedding dates are checked against both partners' charts, and hardest against the bride's. The free tool reads one chart; checking two properly — plus selecting the hour — is exactly what the date selection service is for.

‍ ‍

How to use this for moving house or renovation

Movers and contractors book out weekends, so check early. 成 Succeed and 开 Open days are the classical choices for moving in; renovation start (动土 — breaking ground) specifically avoids 建 Establish days. If your household spans three generations, remember each person's chart can clash a different date — a date that suits you can hit your parents. That's a multi-chart job.

‍ ‍

What this tool honestly can't do

The tool covers the almanac layer and personal clashes against one chart, and it explains every point it scores. A professional 择日 goes further in three ways: it aligns the date's elements with your chart's useful god (用神) rather than the light element check used here; it selects the hour, which the almanac layer doesn't touch; and it checks the venue direction against the year's Tai Sui. None of that can be responsibly automated with a birth date alone — which is why the tool stops where it stops, and why the consult exists.

‍ ‍

One person free. Two or more is a different job.

The checker reads one chart because that's what a tool can do honestly. The moment a second person is involved — a couple fixing a banquet, a family moving house, a household relocating an altar — every additional chart multiplies the constraints, and the answer stops being a score and becomes a judgment call between competing trade-offs. That work is done personally by Master Yuan: see the date selection service, or WhatsApp him with your dates.

  • It reads today the way a printed almanac would, but in plain English: the day's pillar, the Twelve Day Officer governing it, which zodiac sign the day clashes, and what that combination suits and doesn't. If you've entered your birth date it also reads the day against your own chart. It answers "is today a good day" — the date checker below answers "is that date a good date".

  • Intention. The Today card is for the day you're already in — a daily orientation you can check each morning. The date checker is for a date you're choosing, weeks or months ahead, for a specific event like a wedding, a move or an opening. Same almanac engine underneath; different question.

  • It's a tool that evaluates a calendar date against the rules of the Chinese almanac (Tong Shu 通书) — the Twelve Day Officers, clash days and special days — and, if you provide a birth date, against your own Bazi chart. This checker explains every verdict in plain English instead of printing 宜/忌 lists.

  • Yes — checking any date or browsing any month for one person's chart is completely free, with full explanations and no account. Date selection for two or more people is a personal service by Master Yuan, because multiple charts genuinely can't be reduced to a single score.

  • A twelve-day cycle — 建 Establish, 除 Remove, 满 Full, 平 Level, 定 Settle, 执 Hold, 破 Break, 危 Danger, 成 Succeed, 收 Receive, 开 Open, 闭 Close — assigned from the relationship between the day's branch and the month's branch. It is the engine behind the "suitable/avoid" lists in every Chinese almanac. 成, 开, 定 and 满 days favour weddings and openings; 破 days are unfavourable for anything celebratory.

  • Because the almanac is only half the answer. A date that's auspicious in general can still clash your own chart. The tool checks the day's branch against both your year branch (your zodiac sign) and your day branch (the spouse palace) for clashes, punishments and harms, and notes whether the day's element supports your Day Master. Your birth date stays in your browser — it's never sent anywhere.

  • Each day clashes one of the twelve animal signs (日冲生肖) — the branch directly opposite the day's branch. Tradition holds that people born under the clashed sign should keep that day low-key and avoid major personal events on it. The tool always shows the day's clash animal, and warns you specifically if it's yours.

  • The lunar 7th month (roughly August–September) is traditionally avoided for weddings and moves in Chinese custom in Singapore. The tool flags it on every affected day but treats it as a caution rather than a veto — users of other faiths may still want the best almanac date within that month, and the almanac assessment stands on its own. The one exception: fengshui audits, where the seventh month is a hard no rather than a caution.

  • Fengshui practice keeps its own calendar rules. Master Yuan does not conduct audits on the thirteen 杨公忌日 (Yang Gong taboo days), on the eight 四绝/四离 days (the eves of the solstices, equinoxes and season starts, when the seasonal qi is in transition), or on-site during the lunar 7th month. Select "Fengshui audit" in the tool and these days show as red with the reason stated — so you can pick a workable date before you even get in touch.

  • No — arguably the opposite. A lay-low or clash day is a poor day to act: to sign, launch, confront or commit. It is a perfectly good day to reflect and plan — which is what a reading is. If the calendar is telling you to sit still, sitting down to understand your chart is one of the most productive things you can do with the day.

  • The free tool reads one chart. Wedding dates are classically checked against both partners' charts — and hardest against the bride's — which is a genuine multi-chart judgment, not a score. That's the date selection description

  • Yes — all gazetted public holidays for 2026 and 2027 (including observed Mondays) are marked in the calendar, per the Ministry of Manpower, alongside weekend shading. Almanac verdicts work for any date from 2024 to 2030.

  • The day officer, day pillar and clash animal shown here match the printed almanac — they're computed from the same solar-calendar rules, verified against published almanac dates. What differs is the explanation: instead of classical-Chinese activity lists, you get the reasons in plain English, plus a personal layer no printed almanac can offer.

  • Three common reasons: the other site may ignore the month/year clash days (月破/岁破); it may not check the date against your chart at all; or it may use a different school's activity list. This tool shows its reasons line by line, so you can see exactly what's driving the verdict — and take it to a practitioner if you want it refined.

  • No. Hour selection depends on the chart of the person acting and the event's nature, and it's part of what a professional 择日 adds — along with alignment to your useful god and the venue's direction against the Tai Sui. The tool is honest about where the automated layer ends.

  • It covers eight everyday event types, from weddings to travel. It deliberately does not offer birth-date selection of any kind — that is not a service Bazi.sg provides.
