Module:Zodiac date

This module is rated as ready for general use. It has reached a mature form and is thought to be relatively bug-free and ready for use wherever appropriate.

Usage

{{#invoke:Zodiac date|main|sign number|[year]}}

where sign number is the number of the astrological sign, explained in the table below. Year is the year in which the Sun enters the sign; in the case of Capricorn the date for leaving the sign will be in January of the following year. The time scale is UT1, which is similar to Greenwich Mean Time. The supported range is 2015 to 2050, including all the signs in 2050 except Capricorn (because it begins in December and no data is available for the end date of the sign in January 2051).

Value	Sign
1	Aries
2	Taurus
3	Gemini
4	Cancer
5	Leo
6	Virgo
7	Libra
8	Scorpio
9	Sagittarius
10	Capricorn
11	Aquarius
12	Pisces
