How does the lunar cycle work?
The lunar cycle is the moon’s passage period to complete a series of phases, including from the new moon to reaching it again.
This cycle is known as a lunar month or synodic month and has an average duration of approximately 29.5 days.
How is each phase of the moon?
- New moon
At this stage, the moon is between the earth and the sun. The bright part of the moon is facing the sun, making it virtually invisible from the earth. But it is possible to observe your presence in the sky during the day.
- Crescent moon
As the moon moves away from the sun, a thin illuminated slice begins to appear, forming a growing one. This is why it is called the Crescent Moon court, as it is being more visible than before.
- Full moon
At this stage, the moon is directly opposite to the sun in relation to the earth. Its enlightened face is totally visible.
The passage of the full moon is the brightest phase – and when you can see this celestial body completely lit in the night sky.
- Waning
As the moon continues to “decrease in size”, only a thin illuminated slice remains visible before the moon completely disappears from the view of the earth, restarting the cycle with a new moon.
