Recently, while stopped at a traffic light, I noticed the familiar motto “24/7/365” on the back of a taxi. This has always bugged me in many ways.
First, adding 365 only restates the number of days the business is open and adds nothing to the value if 7 is already stated. “24/7” or “24/365” should suffice.
Secondly, shouldn’t it be “24/7/52” As there are 24 hours in a day, 7 days in a week, and 52 weeks in a year?
The final way this bugs me applies to the standard “365 days a year” statement. What happens on the 366th day during leap year? If they were so thorough to mention the number of hours, and number of days (twice), why not specifically state “24/7/if year mod 4 = 0 then 366 else 365”?
However, we still don’t have all of the facts here. Though it won’t affect us adults, only centuries divisible by 400 are leap years. 1900 was not a leap year even though it is divisible by 4. 2000 was a leap year but 2100 will not.
If you have young children start teaching them the correct leap year algorithm now. If you are a coder make sure you check leap year correctly or we could pass a Y2100 bug on to our children.
