# Hsia Calendar
## Introduction

The Hsia Calendar (夏历) is also known as the Ten Thousand Year Calendar (万年历). Unlike the Chinese Lunar Calendar, the Hsia Calendar is a Chinese solar sexagenary calendar system, based on a cycle of 60-years.

## Purpose

For a given date and time of birth, the Hsia Calendar is used to obtain the Heavenly Stems and Earthly Branches with which to construct the Four Pillars of Destiny (四柱) of a person. The Four Pillars of Destiny are also known as the Ba Zi (八字), literally the Eight Characters of a person's birth. In ancient China, one use of this form of divination was to select a suitable marriage partner.
The Four Pillars of Destiny are the Year Pillar, the Month Pillar, the Day Pillar and the Hour Pillar. Each Pillar is made up of two components, namely the Heavenly Stem and the Earthly Branch, both of which are read from the Hsia Calendar.
The Hsia Calendar is also used in various types of Feng Shui, or Chinese Geomancy, such as the Flying Star Feng Shui.

## Seasons

There are twelve Seasons (SS) used in the Hsia Calendar. These are based on the relative position of the sun.
