The Rich History Behind It!
The lunar calendar has been in existence dating back to 32,000 BC.
It has a mathematical basis and with some intercalucations, you can figure it out.
However, if we look at from a historical viewpoint, it is fascinating.
We will look at the archaeological history and the culture that used it to document the constellations, earth’s movement around the sun, and astrological details.

What Is A Lunar Calendar?
To better understand what a lunar calendar is, we must first take a look at the types of calendars there are in our world.
Lunar
⦁12 synodic months (phases of moon)
⦁354.37 days
Lunar-Solar
⦁12 synodic months (phases of moon)
⦁354.3672 days
⦁13 month added every few years to in phase with seasons
Solar
⦁This is what we use today
⦁12 months
⦁365 days
The lunar calendar is based on:
Phases of The Moon
A Lunar month is measured by new moon to new moon.
Various phases of the moon occur in between the new moons and are depicted on a lunar calendar.
The 8 phases of the Moon

Waxing Crescent Moon
⦁The moon has a crescent look and increases in size within a few days period.
First Quarter Moon
⦁One week after new moon.
⦁Half of the moon can be seen.
Waxing Gibbous Moon
⦁Occurs during the time between first quarter and full moon.
⦁More than half of the moon can be seen and increases in size within a few days period.
Full Moon
⦁The entire moon can be seen.
Waning Gibbous Moon
⦁Occurs during the time between the full moon and third quarter.
⦁More than half of the moon can be seen, and the shape decreases in size within a few days period.
Last Quarter Moon
⦁Half of the moon can be seen.

Who Uses The Lunar Calendar?
What’s The Purpose Behind The Use Of The Lunar Calendar?
The moon plays a big part for those that participate in ritualistic practices/activities.
It provides a form of time-keeping for various festivals or rituals that occur within a culture.
History Behind The Lunar Calendar
Up to 40,000 years ago, man began documenting the beginnings of the phases of the moon.
A European culture known as Aurignacians (see image below) was responsible for inventing what we know as the lunar calendar.

An Aurignacian Man
The Aurignacians made many of the lunar calendars on bones; however, stones were also used.
These were designed for portability to be carried on hunting trips or seasonal migrations.
The ancient lunar calendars indicated that there were different phases of the moon.
These phases were counted which determined that this culture had arithmetic skills.
The markings on the bone/stone carvings were carefully controlled in line thickness with a direct correlation to lunar phases.

Modern Day Lunar Calendar
The lunar calendar today looks a lot different than those engraved in bone/stone by the Aurignacians.
If you look at the calendar below, you will notice the different phases of the moon.
