The calendar dates of new moon, full moon, etc. change every year because there aren't an even number of lunar cycles in a year. It's similar to how the day of the week a particular date falls on changes from year to year because there aren't an even number of weeks in a year.
The phases of the moon do not change based on the season. However, the position of the moon in the sky may vary depending on the time of year, so you may see the moon in different phases at different times during the winter compared to other seasons.
Ah, yes, moon phases, what a beautiful topic. People often wonder why does the moon change shape, what causes the phases to occur, and how they can predict or track the different phases. It's a delightful curiosity that many share, and exploring the phases of the moon is a lovely journey to take.
There are eight primary moon phases in a lunar cycle: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent. Since a lunar cycle is about 29.5 days, there are approximately 12 to 13 complete cycles in a year, resulting in about 12 to 13 full sets of these moon phases annually.
It takes about 27 days for the moon to return to it's same position with respect to the Earth, however since the Earth also orbits the sun the moon has to travel around the Earth for about 29 days for it to complete one lunar month.
Some festivals are surely decided by moon phases but not all. Some are decided on how the moon phase is or how many days have elapsed after a particular moon phase. But some festivals are based on dates.

Phases of the moon are caused by the revolution of the moon around the Earth and the revolution of the Earth around the sun. As long as the moon revolves around the Earth as it does, the lunar cycle from full to new to full again will take about 29½ days. We will be having about twelve and a third moon cycles every year until these facts change.
Phase of the Moon on 13 December: waning crescent with 22% of the Moon's visible disk illuminated. Last quarter Moon on 10 December 1998 at 9:55 a.m. Pacific Standard Time.
Orbital revolutions around the earth: Every 27.32 days, or about 13.4 times a year. Cycle of phases: Every 29.53 days, or about 12.4 times a year.
The moon's phases happen every month. Tides happen twice a day. Seasons happen every year. So the only thing that doesn't happen in cycles is gravity.

Google this: calendar of moon phases (insert month and year here)
Yes in a general sense it does but it does not follow the Gregorian calendar directly. As a result, a full moon can occur on any date of the year however many religious observances, such as the date of Easter, is wholly determined my the lunar phases, which is why Easter lands on a different date every year.
No. The Moon circles the Earth every 27 days, or roughly 13.5 times per year. That means its phases don't and can't match up with calendar months.
The Moon's phases are not the same every year. One year, Jan. 15 might be a full moon, some other year new moon, etc.__________________________________If you go to the web site http://aa.usno.navy.mil/data/docs/RS_OneDay.php and enter in your birth date, it will tell you the phase of the Moon on that date.
the process that causes the moon to appear at these different phases of earthlings
The moon has many different phases that it goes through multiple times throughout the year. The two factors that cause these phases are its position in relation to the Earth's shadow. The second one is the position of the sun in relation to the moon.
