Adding to this, if you are dealing with dates in JavaScript specifically I recommend going further and doing all business logic with the UTC timestamp stored as a number / unix epoch, and only doing `new Date(timestamp)` when you need it in local time, like right before rendering on the page or something as you mentioned.

It obviously depends on your use case but I find most time operations are often easier to deal with as pure mathematical operations. I will reach for Date when I need to deal with weird stuff like the day of the week but having burned through so many footguns with what I consider the worst DateTime API I have ever dealt with in any language, I will do anything I can to avoid using it.

Some libraries like date-fns can help here, but can't always bring in new deps easily. I hope the new temporal API fixes things.
