Explanation:
Two days ago, I biked my first outdoor imperial century (AKA over 100 miles), but didn’t immediately take a picture of my watch displaying the data as I usually do.
Today, I tried to access it and found out that the watch deletes all data weekly and considers Sunday the first day of the week.
What it has to do with Christianity:
It makes absolutely no sense to consider Sunday the first day of the week rather than Monday. Unless you follow stupid standards established by people who consider the last day of the weekEND holy and thus want to give it pride of place as the starting day rather than the final day of the week.


Did you read the manual of the watch before you started using it?
When I got the watch several years ago, yes, long before I got an outdoor bike and started recording workouts with it six months ago.
Does it mention that as far as this watch is concerned the week starts from Sunday?
