It takes 29.531 days. (rounded)
That's the time required for the moon to physically orbit the Earth (27.32 days),
plus the extra part of the orbit that it has to cover to make up for the roughly
27 degrees that the Earth has moved in its orbit during that time ... since the
visual 'phases' are all the result of our positions compared to the sun.
The moon displays a complete cycle of all its phases every 29.53 days.
The 'waxing gibbous' phase does.
The next new moon.
The lunar cycle of phases is about 29.5 days. As the moon rotates and revolves around the earth, and the earth rotates and revolves around the sun, the shadows cast by the shifting positions of the moon and earth cause the moon to wane, wax, and "disappear". This is known as the lunar cycle.

The moon will be a full moon, halfway through the lunar cycle.
One lunar cycle is when the moon goes from one phase through every other phase until it returns to the starting point. This takes 29.53 days.
The next new moon.
The lunar cycle of phases is about 29.5 days. As the moon rotates and revolves around the earth, and the earth rotates and revolves around the sun, the shadows cast by the shifting positions of the moon and earth cause the moon to wane, wax, and "disappear". This is known as the lunar cycle.
That would be the New Moon phase of the lunar cycle.
The Waning Phase in the lunar cycle occurs as the moon shrinks from the Full Moon to the New (Dark) Moon. Note: You can tell when you are in the Waning Phase when the Left Side of the Moon is illuminated. Conversely, if the Right Side is illuminated, the Moon is Waxing.
There is no "last" in repeating cycles. Whatever phase you are thinking of, the next one restarts the series.

A complete cardiac cycle.
