The duration of daylight wanes to the Winter Solstice and waxes to the Summer Solstice. From the equator, these two dates would have little to no distinction, while from either of the Earth's poles, this difference would consist of a complete 24 distinction.
The time of the Moon's rising and setting will also vary at different places on the Earth, as well as with the irregularities of the Moon's cycle.
The time of the Sun and Moon's rising and setting is averaged in this display, such that the Sun is always shown to rise at 6 AM and set at 6 PM, and the Full Moon is shown to pique at midnight, while the New Moon piques at midday.
Due to the Moon's elliptical orbit around the Earth and its shifting pericenter, accurate predictions of the Moon's exact phase require calculations of humbling complexity.
This calendar is currently using the Moon cycle's average duration of 29.530588853 days to calculate phases for a given date from the known New Moon on August 7th, 1970. This means that exact phases have a margin of error of up to several hours, increasing as the date of prediction moves further from 1970.
If you were to draw a line from the Earth through the Sun and then continue this line through space, the constellation that it points towards is considered to be the current "Sun Sign" at this point in the Earth's revolution- or at this time of the year.
When the Sun is said to be "in a sign," that constellation will not be visible from Earth, since it is hidden behind the Sun's glow. Instead, each constellation is best seen in the night sky approximately three months prior its phase.
