What time is it? It’s Sunday
A wall clock is an old-fashioned tool used to tell time, just in case you haven’t seen one ever. However, they’re not very helpful when it comes to telling other things like the day. However, if you have even the slightest clock-making skill, you can fashion a day-telling clock, just as this person did.
Now, we’re not entirely sure whether this clock can also be used to predict the time based on how far the needle is into the day. We hope that one day, someone creates a clock just like this but can tell what the month is instead. Now that would be helpful.
