Project mention: A bug which is only a bug five days out of the year | news.ycombinator.com | 2024-01-31

To be honest, use a library where someone else figured out the ambiguities and accounted for the edge cases. Good starting point: https://moment.github.io/luxon/#/math
Date-fns is fine for simpler use cases but Luxon is a lot more complete, especially where it comes to time zones.
