Discover How a
Lunar Clock Works
Have you ever considered how it would be if we kept time
depending on the Moon’s position instead of the Sun?
Now the purpose of developing a Lunar Calendar is for it to be
made use of by settlers on the Moon. It is quite different
from the one that we employ on Earth. If you reside on the
Moon, then you will require one, but otherwise not. However,
you can at least support the concept.
Well, the Lunar year comprises of twelve days, and these are
named after the earliest men who touched down on the surface
of the Moon. A day is split into thirty time cycles, and each
cycle is further split into twenty-four moon-hours. Now, each
moon-hour is made up of sixty moon-minutes, and these in turn
naturally consist of sixty moon-seconds each. Moreover, the
conditions on the Moon’s surface are rather different from the
conditions on the Earth. In the first place, there is
continuous daylight for around fifteen days and there is total
darkness for the next fifteen.
A sphere-shaped mass of rock goes around the Earth and this
has a gravitational pull that has an effect on all aspects of
life on Earth, including our own body clock. The Moon takes
twenty-eight days to go around the Earth and this results in
tidal changes, sometimes hiding from view the sun's rays, and
producing spiritual and mental mood swings in individuals.
The Cycles
In order to discover the way a lunar clock operates we have to
be aware of the cycles, which the moon moves in. Every
twenty-eight days, the moon passes through five different
cycles. For a single day, the New Moon occurs and this comes
amidst the Waning and Waxing Moon. Now the length of a Waning
Moon approximately is fourteen days and this happens to be the
time when the moon changes from the Full Moon to the New Moon.
Moreover, the Waxing Moon’s length too, is nearly fourteen
days and it is the period that occurs between a New moon cycle
and a Full cycle of the moon. Also, the Full Moon occurs only
for a single day. Now, the three days before the Full Moon
(i.e. portion of the Waxing cycle) have a much powerful
gravitational pull including the day of the Full Moon. Now the
length of these is not precisely twenty-eight days as at
times, the Waning or the Waxing cycles take a lesser time
period.
The Phases
Each cycle of Waxing, New, Waning, and Full has within them
phases that they pass through. It is not possible to actually
perceive a New moon in the sky irrespective of the lateness of
hour. This is at times called the Dark Moon. While the moon
moves into the Waxing cycle you will start to observe a sliver
come into view until it develops into a Full Moon. Once the
moon commences its Waxing cycle, it is at times called the
Crescent Moon. Now one way to find out when exactly the moon
Waxes and Wanes is by noting on which side the dark side
becomes visible. When the Moon waxes, the dark side becomes
visible on your left with the Waxing Moonlight shining to the
right. It is for a very brief period that the Waxing Moon can
be observed in the sky, like at sunset.
Once the Moon develops into a completely round sphere, it is
called Full Moon. Now it will ascend nearly exactly when the
sun sets and will become invisible just about when the sun
rises. In fact, this is the least difficult Moon cycle to
identify. A Waning Moon occurs when a Full Moon shrinks in
size down to the New Moon. Now for around three days preceding
and three days succeeding, the Moon still looks like a full
one. But, if one is sharp-eyed you will be capable of making
out the subtle changes as they take place every evening. On
the right, the Moon starts to fade away and appears brilliant
on the left. This is in total contrast to the Waxing Moon.
A simple method of memorizing the cycles is that when the Moon
waxes it becomes large and when it wanes, it starts to get
smaller.
On 21st July 1969, Neil Armstrong touched down on the surface
of the Moon at 02:56:15 UT. For a calendar to commence, this
point in time is the apparent choice. Hence, this is Year 1,
day 1 cycle 1, 00:00:00
What is the need to comprehend this? Each moon phase exerts a
varying gravitational pull and in the same way as those
varying energy forces impact the tides, they also have an
impact on you.
