As a Real Programmer(tm) I have developed such a deep fear of anything time and date related that I would fully endorse dispatching an API call to the tz_database instead of attempting any fucking part of this.

Kids, it's fine to meme about silly stuff... but date and time is deadly serious, regardless of how careful you think you're being you are wrong.

Do you know how many timezones there are in Indiana? No? Look it up and scream in horror.

What if I told you that weekend days are locale dependent?!

Time and date is the black hole where optimistic programmers go to die. Nothing is simply with localisation and if you think it is, you mustn’t have worked enough with it.

Source: Run a system that schedules millions of interactions across the world and deeply depend on this. The amount of code to manage and/or call out to external services to give us information about time zones, summer time, locale specific settings, day names, calendar systems, week numbers etc etc.

You want to expand your business to Europe. Bam, your code is broken, in Europe the week starts on Monday.

Than you want to expand to the middle east. Bam, broken again... Because in arab countries and Israel, the weekend is on Friday and Saturday.

Then you want to expand to Mexico and India. Bam, broken again, their weekend is only on Sunday.

The obvious solution is to inject an IWeekendDaysOfWeekProvider service in the inversion of control container. In your, uh, javascript web app.

Just npm install isWeekend for the required locales.

Depends on: isMonday, isTuesday,...

I'm English, not American but I see it as Saturday and Sunday are the two ends of the week. Like how a string has two ends. The weekend is both the start and the finishing end of the week.

So, when someone asks if you are free the next two weekends, you assume they're talking about the next Saturday (tail weekend) and the next Sunday (front weekend)?

Why would you call it weekend and the start the week with half of it?!

A rope has two ends, and so does a week
