The waxing phase of the moon is the period of time between new moon and full moon, where the size of the illuminated portion of the moon is increasing. The waning phase of the moon is the period of time between full moon and new moon, where the size of the illuminated portion of the moon is decreasing.

The waxing phase of the moon is the period of time between new moon and full moon, where the size of the illuminated portion of the moon is increasing. The waning phase of the moon is the period of time between full moon and new moon, where the size of the illuminated portion of the moon is decreasing.
The period between a full moon and a new moon is approximately two weeks, known as a lunar cycle. During this time, the moon transitions from being fully illuminated to completely dark before beginning to wax again.
Moon's phase cycle from New Moon through to Full Moon takes 29.53 days. More details are on the related link (Click 'Lunar phase' below)
29.53 days
The synodic period of the Moon is about 29.5 days, representing the time it takes to go through a complete cycle of phases as observed from Earth. This period defines the time between successive occurrences of the same phase, such as from full moon to full moon. The slightly longer synodic period compared to the Moon's orbital period is due to Earth's motion around the Sun.
The time period between Full Moon and Third Quarter is usually 7 or 8 days, depending on the actual Full Moon and Third Quarter times.
When the Moon is "waxing", it is increasing in visible size. This is between the new moon to the full moon. When the Moon is "waning" it is decreasing in size, from the full moon to the new moon.
When the moon grows smaller, it is said to be waning. This is the period between the full moon and the new moon, when the visible portion of the moon decreases.
On average, it takes about 14.77 days for the Moon to transition from a full moon to a new moon. This period is known as the synodic month and represents the complete cycle of the Moon's phases as seen from Earth.
