A D3.js stylish data-driven moon calendar project that displays the phases of the moon from my birth year of 1997 to the present day of 2022.
It is available to check out on GitHub Pages.
Time and Date was used to get the data from the moon phases. Kalender-365 was used to confirm findings on the first site. I thus had to enter manually all the 4 phases of the moon, and the year, month and day they occured in a CSV file.
I also took note of the percentage of lighting the moon is recieving (0, 50, 100, -50), which I converted to a multiple of pi (0, 0.5, 1, 1.5). The CSV file was about 1'200 rows long.
I first tried to automate the display of the moon between the 4 phases, but soon realised the time between them was not regular; it could vary from 5 to 8 days in-between two phases. As such, I calculated by hand the multiples of pi for the moon in-between the 4 phases. All is put in the CSV file, on which I then iterate to display the lunar calendar for each months. In the end, pi multiples span from 0 to 1.999, and the CSV file is 9'496 rows long.
