December 4, 2014 · 09:00–11:00 (Si hour · Snake)
The Si hour · Snake double-hour (09:00–11:00) completes Thursday, December 4, 2014 with a fourth, hour pillar: 甲午 · 乙亥 · 己酉 · 己巳.
Answer first: the reference four pillars for 2014-12-04, 09:00–11:00, are year 甲午, month 乙亥, day 己酉, hour 己巳. 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.
Yang Wood Horse · Jia Wu
The visible stem is Jia · Yang Wood; the branch is Wu · Horse · Fire. Its Na Yin is 沙中金, and the branch contains hidden stems 丁 · 己. 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 (09:00 or 11:00) 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 2014-12-04 09:00–11:00
What is the hour pillar for 09:00–11:00 on Thursday, December 4, 2014?
In this civil-clock reference, the 09:00–11:00 double-hour on 2014-12-04 carries the hour pillar 己巳 (Yin Earth Snake), completing the four-pillar record 甲午 · 乙亥 · 己酉 · 己巳.
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.
