How to generate the Day Number of the Year

[Aladdin2020]

Hi,

I want to generate the Day Number of the Year, currently I was able to generate the day of the week of any date, input the date and the out put will be Tuesday, Monday, etc.

How can I generate the day number like  06/22/2020 = 174 or 07/01/2020  = 183 etc. and keep account of the leap year of any date? any ideas or feedback are appreciated! 

Thanks

How old is that code? The format of the "date time rec" cluster has changed decades ago, so I recommend to use the current version.

See if this works for you:

(I am not sure why you have a while loop without any wait. I doublet it is necessary to recalculate the same input millions of times per second)

Thank you for your help. the code is exactly what I need!

That code could be reduced to the size of a couple of postage stamps. Somebody wise once said, do more with less. All you need is the %j specifier.

How do you enter an arbitrary day/month/year into the three given controls??

(e.g. for 07/01/2020  = 183)

I did not enter anything into the controls. It can be done like below, just use %j for Julian Day; this is pretty close to the OP's original request, a string result.

Oh, no insult felt here 🙂 Always enjoy creative wording. 🙂

I would argue that unbundling "day of year" is easier to read for most. Code size is similar. It also depends if we want a numeric or string.
