Here's the overview:
1. Use the lunar cycle constant `29.53058770576` and calculate its duration in seconds as `lunarSecs`.
1. Use the lunar cycle constant `29.53058770576` and calculate its duration in seconds as `lunarDays`.
2. Convert date of first full moon in 2000 (January 6 at 18:14 UTC) to unix timestamp as `lunarSecs`.
3. Calculate `totalSecs` which is the time (in seconds) between the user date and the moment of the first new moon in 2000
4. If the result is positive, it's valid, so calculate the modulus (remainder) of `totalSecs` divided by `lunarSecs` , to know the amount of seconds that have passed in the current cycle as `currSecs`.
3. Calculate `totalSecs` which is the time (in seconds) between the user date and `lunarDays`.
4. If the result is positive, it's valid, so calculate the modulus (remainder) of `totalSecs` divided by `lunarSecs`, which will return the total seconds that have passed in the current cycle as `currSecs`.
5. Divide `currSecs` by `lunarSecs` to find the current position in the lunar cycle as `currentFrac`.
6. Multiply `currFrac` by `lunarDays` to get this value in days as `currDays`.
7. Find the correct moon phase based on the value of `currDays`.

Since we're going to want this app to stay updated automatically, the math is going into a function named `updateIcon()`. This is the `key` we're going to pass to the `buildMenu()` function we already built.
First, we're going to get the curren system date and time with [Date](https://developer.apple.com/documentation/foundation/date). This is always in UTC.
