That’s not so much a Christian thing as a US thing as far as I know. In most European countries Monday is considered the first day of the week.

This is unintentionally funny:

I imagine you sitting in front of your clock, screaming “those damn christians”.

I would have posted something like “I did not understand the data management of my clock and sadly lost my most valuable dataset”. Maybe sweep in front of your own door before blaming your neighbors.

Hold up, why does the watch delete the data weekly? Surely this is the actual problem.

what? Nope you are wrong. Monday is the first day of the week all over Europe. Blame Americans not christians, at least this time.

This is Wear OS, right? The Google smartwatch OS. That’s the company that made it a business to aggregate all the data in their cloud so people wouldn’t leave their services for convenience alone.

And you’re telling me that you think that the only way to get data off that clock is to take a picture of it before Sunday?

Workouts this week being 0 doesn’t mean that the data isn’t there, it’s just giving you a summary for the ‘calendar’ week.

You should be able to find the activity still. You should also be able to change when the start of the week is. (It’s an option you see everywhere)

Sounds more like a bad watch or setting it up badly. Why would it delete anything anyways before backing it up on secondary media or in general?

Workouts are usually .gpx files which are kB in size. You cannot tell me there is no space on the watch for that. Mine stores all workouts I have ever done.

While it has nothing to do with that (US uses Sunday as first day, Europe uses Monday as first day) it just resets weekly but the data is still there. You need to connect it to its app, maybe even Gadgetbridge if you’re lucky (don’t know what watch is yours). Also I’m pretty sure it has an option to change the first day of the week (usually in the app).

In many languages the days are numbered, e.g. “First day”, “Second day”, …, “Seventh day”. Speakers of those languages have no question about when the week starts.

Notably, the older languages start the week on Sunday. Some of the languages that start the week on Monday can be attributed to mistranslation from the former group. So starting the week on Sunday is historically more correct.

Disclosure: I speak a language that starts the week on Sunday, so I’m biased.

If you look at the bottom you’ll notice the watch has correctly identified you as operating in beta mode. You should practice mindfulness to be more aware of what’s going on around you e.g. your watch’s settings.

It makes absolutely no sense to consider Sunday the first day of the week rather than Monday.

Think about how bookends are supposed to be placed on a shelf. Now, imagine they are weekends instead of bookends.

America was conquered and colonized by Europe, so has a European heritage. In Europe Sunday was a rest day at the start of each week, so they would start their week clean (and yes, because of Christianity because they would be blessed on Sunday and confess in church to get rid of their sins). Later the Saturday was added as a work free day, now in some countries another day is added although it’s not specific (people can chose which days they want to work).

In Europe they switched to a Monday as the first day of the week, as people tend to start their week with work on Monday and companies also see Monday as the first day instead of a Sunday. Just because we switched doesn’t mean everyone switched. And the US usually holds on to old customs, like imperial measuring system.

Most things in society come from Christianity. Like most holidays, how we count years, many values and standards, etc. Christianity is in the roots of our society. It’s a large part of the building blocks in society, the roots from history. I’m happy it’s not that big of a deal anymore these days, although in my country it’s much less than in the US for example.

But to blame Christianity for you not changing the default first day of the week settings I believe is a bit strange.

It’s like the use of . And , notations in numbers, or how you write dates (first the day then the month, or the other way around). There are some standards per region / country but usually you can just change these settings.

Are you also angry the days are named after Roman gods?

By the way, originally in Christianity the holy day was a Saturday, the Saturday Sabbath (originating from Judaism). In paganism the holy day was the day of the sun, namely Sunday. But to avoid a religious war with pagans, emperor Constantine gradually changed the holy day for Christians to a Sunday, among other things, to blend both religions together instead of clashing. It’s called the Constantine’s Edict (321 CE): Emperor Constantine issued an imperial law declaring Sunday (“the venerable day of the Sun”) a day of rest for all citizens.

So maybe you should blame paganism or emperor Constantine.

Or just change the settings.

I’m an atheist, I dispise religions and cults (same thing in my eyes) but your post feels like you’re searching to blame them for anything, in this case something stupid, while religion still is the cause for so much awful shit in the world. So why not focus on the real religion caused issues instead?

That’s why you always go through all the settings first thing, to find weirdness like that.

Did you read the manual of the watch before you started using it?
