Notes > Writing dates and times

By accident, I discovered that Google Translate translates a date format of dd.mm.yyyy to mm/dd/yyyy. It’s unclear whether there is an established standard of using slashes for month-first dates and dots for day-first dates, but such a standard would eliminate great confusion. Below is a (non-exhaustive) list of date and time formats along with my preferences boldened.

In this website, I will use the following date formats for referencing -
year: YYYY-XX-XX, month: YYYY-MM-XX, day: YYYY-MM-DD.
X is the literal X. For examples, go back to ~/notes.
