I think this would satisfy my needs. Let me explain.
All numbers (Nr, Border1, Border2) will be positive integers.
There never will be a zero. If it was, then the calculation is wrong. Or the watch generated incorrect starting numbers that form the pre-calculation that derives Border1 and Border2 which is calculated way before this test. If the watch generated bad numbers to start the calculation, there is something really wrong with the watch. However, even if the numbers were really wrong, the calculation should actually still generate positive integers for Border1 and Border2. A quirk of the calculation.
The calculation will only generate a border 1 and border 2 numbers that are always going to be around 70ish and 300ish respectively. Therefore, no zero cross over. The overall calculation for this test is not actual clock time, therefore, hours are irrelevant for this test.
Nr will always be a positive number as it is the day number which is between 1 and 365 or 366. Therefore, no zero crossover.
Given these limitations, I don’t think the calculation would ever generate a non-answer, Nr would fall either within the borders, resulting in answer A or by default answer B.
Anyways, thank you all for helping out. I’ll run the test and see what happens. But I’m a long way off to even getting to this condition.
Yes. Overlapping True. The big copy paste trap in the serial conditional panacea. My main overlap is forgetting >= and <= (or a number [in/de]crement in the comparison.
Here is the next GMT version. This time, all zones will automatically reflect Daylight Savings changes. PLUS, this version also will notify when Western Easter Sunday. Which btw is on April 20th, just in a few days.
Sorry. Accidentally deleted my own post. What a dummy. If you are interested in figuring out Easter Sunday notification calculation. I’ve posted a solution here.
BTW, if you want a face with a set of different time zones, Let me know and I’ll see if I can create it. I don’t have the pro versions, so I can’t create a user adjustable/selectable zone version. Maybe one day.
Tres Cool! better than anything I first made, I just found a subject image I liked, and slapped some hands on it. Come to think of it, I still do that, I just do a little photoshop tweaking here and there now.
