Birthheight

Birthheight is plotting of people on the using s and. Using coordination between determined by birthdate and  determined by height, then  and consequently caelregio a person is can be plotted.

Definition
On the celestial map, the right ascension represents the birthdate, the declination represents the height. A 2h interval of right ascension represents an interval of 1 month. A 7.5° interval of declination represents an interval of 1 inch. A taller person is north of a shorter person. A person with a later birthdate is east of a person with an earlier birthdate.

On the, the height is 56 (1.00 ta, 167.64 ), the is 6'6" (1. ta, 198.12 cm), and the  is 4'6" (0. ta, 137.16 cm). In a 365-day year (so-called ), on the, the birthdate is January 1 @ 12:00 AM, the is April 2 @ 6:00 AM, the  is July 2 @ 12:00 PM, and the  is October 1 @ 6:00 PM. In a 366-day year (so-called ), on the, the birthdate is January 1 @ 12:00 AM, the is April 1 @ 12:00 PM, the  is July 2 @ 12:00 AM, and the  is October 1 @ 12:00 PM.

"Birthheightsex"
The plotting between birthdate and height can be combined with sex. A "northern boy" is a boy or a man taller than 5'6", which is in the northern hemisphere on the celestial map. A "southern boy" is a boy or a man shorter than 5'6", which is in the southern hemisphere on the celestial map. An "eastern boy" is a boy or a man with birthdate between January 1 and July 2 @ 12:00 PM (between January 1 and July 1 in leap years), which is in the eastern hemisphere on the celestial map. A "western boy" is a boy or a man with birthdate between July 2 @ 12:00 PM and December 31 (between July 2 and December 31 in leap years), which is in the western hemisphere on the celestial map. A "northern girl" is a girl or a woman taller than 5'6", which is in the northern hemisphere on the celestial map. A "southern girl" is a girl or a woman shorter than 5'6", which is in the southern hemisphere on the celestial map. An "eastern girl" is a girl or a woman with birthdate between January 1 and July 2 @ 12:00 PM (between January 1 and July 1 in leap years), which is in the eastern hemisphere on the celestial map. A "western girl" is a girl or a woman with birthdate between July 2 @ 12:00 PM and December 31 (between July 2 and December 31 in leap years), which is in the western hemisphere on the celestial map.

An "equatorial boy" is a boy or a man with their height of exactly 5'6"; an "equatorial girl" is a girl or a woman with their height of exactly 5'6". A "nadir boy" is a boy or a man with their birthdate taking place at nox on January 1; a "nadir girl" is a girl or a woman with their birthdate taking place at nox on January 1. A "zenith boy" is a boy or a man with their birthdate taking place at noon on July 2 (at nox on July 2 in leap years); a "zenith girl" is a girl or a woman with their birthdate taking place at noon on July 2 (at nox on July 2 in leap years).

Example
The birthdate for is July 19 @ 1:11 AM and his height is 5'4"10.6‴ (0.9831 ta, 164.80 cm). This implies that his right ascension is 13:9.2:0 and his declination is −8.36°. This coordinate would be located in the constellation, which is in the caelregio Noctua.

Average heights around the world
The average height around the world is near the celestial equator. In the, the average height is about 5'6"8‴ (1.010 ta, 169.3 cm), which equates to the declination of +5°, which is taller than most countries around the world. The tallest country is , which has the average height about 5'9"6‴ (1.053 ta, 176.5 cm), which equates to the declination of +26.25°. The shortest country is, which has the average height about 5'0"0‴ (0.910 ta, 152.5 cm), which equates to the declination of −45°.
