January 10, 2022 · 07:00–09:00 (Chen hour · Dragon)

The Chen hour · Dragon double-hour (07:00–09:00) completes Monday, January 10, 2022 with a fourth, hour pillar: 辛丑 · 辛丑 · 癸亥 · 丙辰.

丙辰hour pillar · Yang Fire Dragon

Answer first: the reference four pillars for 2022-01-10, 07:00–09:00, are year 辛丑, month 辛丑, day 癸亥, hour 丙辰. 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.

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 (07:00 or 09:00) 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 2022-01-10 07:00–09:00

What is the hour pillar for 07:00–09:00 on Monday, January 10, 2022?

In this civil-clock reference, the 07:00–09:00 double-hour on 2022-01-10 carries the hour pillar 丙辰 (Yang Fire Dragon), completing the four-pillar record 辛丑 · 辛丑 · 癸亥 · 丙辰.

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.
