In which phase is the Moon 66 days before the Lunar eclipse? The expert answer is shown in the attached picture but I don’t understand the answer. Is the final answer a first quarter? Because the moon would have made two complete cycles and it should have started 7 days before the full moon which I think is third quarter?

In which phase is the Moon 66 days before the Lunar eclipse? The expert answer is shown in the attached picture but I don’t understand the answer. Is the final answer a first quarter? Because the moon would have made two complete cycles and it should have started 7 days before the full moon which I think is third quarter?

It can be known that the lunar cycle, or the amount
of time it takes for the Moon to go through all of its
phases, is roughly 29.5 days to figure out the phase of
the Moon 66 days before a lunar eclipse.
Here's how to figure it out:
Step3
c)
5G
Determine the Moon's phase at the time of the lunar
eclipse. Since lunar eclipses normally take place
during a Full Moon, when the Earth is directly
between the Sun and the Moon, let's suppose that it is
a "Full Moon" at the time of the eclipse.
Calculate how many lunar cycles (29.5 days each)
there are in a 66-day period. In order to do this,
divide 66 by 29.5:
2.237 cycles/66 days (29.5 days/cycle)
Since a lunar cycle cannot be divided into fractions,
it can be rounded to the next whole number, which is
2.
Now, to determine how many days remain, divide the
66 days by two moon cycles (2 * 29.5 days = 59 days):
59-66 = 7 days.
