The Moon's phases don't change on specific days of the month, but rather over a period of about 29.5 days, which is the length of a lunar cycle. Here's a breakdown of the phases:

1. New Moon: The Moon is not visible because it's between the Earth and the Sun.

2. Waxing Crescent: The Moon begins to appear as a thin sliver of light, growing larger each day.

3. First Quarter: The Moon appears as a half-circle.

4. Waxing Gibbous: The Moon continues to grow larger, becoming more than half illuminated.

5. Full Moon: The entire face of the Moon is illuminated by the Sun.

6. Waning Gibbous: The Moon begins to decrease in size, becoming less than half illuminated.

7. Last Quarter: The Moon again appears as a half-circle, but now the illuminated portion is on the opposite side.

8. Waning Crescent: The Moon continues to shrink, becoming a thin sliver of light before disappearing completely.

To know the exact dates and times of the Moon's phases in a specific month, you can:

* Use a moon phase calendar: Many online calendars and apps provide detailed information about the Moon's phases.

* Consult an astronomy website: Websites like NASA or Time and Date offer accurate moon phase data.

Remember that the Moon's phases are a result of the changing angles at which the Sun's light illuminates the Moon as it orbits the Earth.
