May 12, 2000 · 05:00–07:00 (Mao hour · Rabbit)

The Mao hour · Rabbit double-hour (05:00–07:00) completes Friday, May 12, 2000 with a fourth, hour pillar: 庚辰 · 辛巳 · 庚午 · 己卯.

己卯hour pillar · Yin Earth Rabbit

Answer first: the reference four pillars for 2000-05-12, 05:00–07:00, are year 庚辰, month 辛巳, day 庚午, hour 己卯. The hour stem is derived from the day stem by the standard five-rat rule. This is a deterministic calendar record, not a personal reading.

Four coordinates, four jobs

What the four reference pillars contain

Each stem-branch pair is a deterministic calendar coordinate. The hour pair inherits its branch from the double-hour and its stem from the day stem, so it stays consistent with every other hour page of this date.

庚辰Year pillar

Yang Metal Dragon · Geng Chen

The visible stem is Geng · Yang Metal; the branch is Chen · Dragon · Earth. Its Na Yin is 白蜡金, and the branch contains hidden stems 戊 · 乙 · 癸. Open the full Jiazi record →

Calculation boundary

What this hour reference does not settle

This page uses a standard civil clock so double-hours can be compared consistently across dates. A real birth happened at a place and an instant, not inside a URL slug.

  • True solar time: the reference assumes a standard-meridian civil clock. Birthplace longitude and the equation of time shift the effective hour, and can move the resolved pillar to a neighboring double-hour.
  • Hour boundary: a clock time within the correction margin of an odd-hour boundary (05:00 or 07:00) is boundary-risk until resolved against place.
  • Zi-hour school: the 23:00–01:00 slot follows the early-Zi convention. Late-Zi schools push 23:00–24:00 onto the next day pillar; neither this page nor the atlas settles that debate.
  • Interpretation: one four-pillar record does not determine personality, career, relationships, wealth, health, or events. It is a coordinate, not a verdict.

Questions about 2000-05-12 05:00–07:00

What is the hour pillar for 05:00–07:00 on Friday, May 12, 2000?

In this civil-clock reference, the 05:00–07:00 double-hour on 2000-05-12 carries the hour pillar 己卯 (Yin Earth Rabbit), completing the four-pillar record 庚辰 · 辛巳 · 庚午 · 己卯.

Why does the Zi hour list 23:00–01:00 as one range?

The Zi double-hour spans midnight in the classical two-segment form 23:00–01:00. This reference adopts the early-Zi convention: 00:00–01:00 belongs to the same civil date. Schools that use the late-Zi convention assign 23:00–24:00 to the next day pillar, which can change both the day and hour pillar; that difference is an open school boundary, not an error.

Is this my personal hour pillar?

Not necessarily. This page is a civil-clock reference at a standard meridian. A personal chart resolves your birthplace longitude, historical timezone, and true solar time, and any of those corrections can move the resolved hour pillar to a neighboring double-hour.

What happens near an hour boundary?

A clock time within the correction margin of an odd-hour boundary (01:00, 03:00, … 23:00) can resolve to the adjacent double-hour once longitude and equation-of-time corrections are applied. Use the calculator to see the resolved pillar and its boundary-risk flag.
