Personal Elements Blueprint

How the calculation works

Four steps, all of them inspectable: your birth moment is converted to True Solar Time for your city; the four calendar columns are derived from the traditional calendar; the five elements of those eight characters are counted; and the result is turned into one small thing you can actually do today. Every convention we use — solar-term month boundaries, the midnight day rollover, and the treatment of hidden stems — is written down below so you can disagree with it.

Questions people ask

What does this calculator actually compute?

It converts your birth date, birth time and birth city into the four calendar columns of the traditional Chinese calendar (year, month, day and hour), then counts the five elements across the eight characters to show your elemental distribution. Nothing is predicted.

What is True Solar Time and why does it change the result?

Your birth moment recorded on a clock is standard time for your time zone, but the sun is not on the same schedule everywhere in that zone. True Solar Time adds the longitude correction for your city plus the equation of time for that date — together usually less than an hour. If the correction pushes your birth time across a two-hour boundary, the hour pillar changes, and with it the hour element.

Do months follow calendar months or solar terms?

Solar terms. The traditional calendar starts a new month at a solar term, not on the first of the month, so the month pillar can sit a few days before or after a calendar boundary. We use the solar-term rule and state it openly rather than hiding it.

Does the day roll over at midnight?

Yes — in this version a birth time between 23:00 and 24:00 still belongs to the same day. Other schools move the day pillar forward at 23:00. If that applies to your case, your day pillar may differ by one; the convention we used is shown with your result.

Are hidden stems (藏干) included in the element distribution?

No. We count the element of each of the eight characters — the four heavenly stems and the four earthly branches — and we do not weight the elements hidden inside each branch. Schools differ on how much weight hidden stems carry, and we would rather show you a transparent method than a precise-looking number we cannot defend.

Does this tell me what will happen?

No. It is a reflection tool built on a traditional calendar calculation. We describe a distribution and suggest one prompt for the day. We do not tell you what will happen, and we do not give advice about your health, money, relationships or work.
