Calculation of Julian Date

Can I get a value/ display Julian date of present day?

Remind us what's the Julian date?

Is that Day in Year combined with the year, like
Clock1.FormatDateTime(Clock1.Now(), 'yyD' ?

Or is it the one used by astronomers?

(see SimpleDateFormat (Java Platform SE 7 ) for formatting codes)

It is the second one, which is used by astronomers.

You should be able to calculate it using the formulas at Julian day - Wikipedia
and the value of Clock1.SystemTime.

Do you need math help?

Let me try first, I will let you know if I need any further help. Thanks for guidance.

I browsed the article I mentioned earlier.

You have opened a can of worms.

There are at least a dozen different kinds of Julian date.

Be sure you and your users are on the same page.

I have got the right calculation and also verified the number from online available calculator. both values are exact match, now the final value is displaying as scientific notation, I want the result as full integer, is there any function which can convert it to string or something?

Code lock is below:

Result format is:

Look in the math blocks section for a FORMAT AS DECIMAL block. Give it 0 fractional digits.

Also, use external sockets for each math block, to avoid the torn sail appearance of your blocks and to help show their nesting vertically.

2.45E6 is about 2 million.

2 million days is a long time historically (Adam and Eve?) , and a short time astronomically.
Are you SURE you have the right formula?
