Date to Julian Format
Hello,
I have the following code:
date = "12/19/2019"
$date = Carbon::parse($event->data['date']);
I would like to convert this to a Julian Date
20001
I just cannot find anything to easily convert this to julian.
Thanks in advance.

You can also find more useful things you can do with the date here: https://www.php.net/manual/en/function.unixtojd.php
For example the unixtojd only returns the day, not the time and so on.

Thankyou for the links but that is creating a Julian Day not Date.
So todays Juian Date is 19336
I need to convert "12/19/2019" to 19336
or simple get the day number from the year so 336 for today

How about this instead then?
https://www.php.net/manual/en/function.gregoriantojd.php
$jd = gregoriantojd($date->day, $date->month, $date->year);

I get the feeling that we're all googling for you, have tried googling this stuff yourself?

Indeed. "Julian day php" :)

Julian is simply the last two digits of the year and the day of the year, seems like it ought to be pretty easy to sort that out on your own with carbon and a little string manipulation
Carbon has a dayOfYear() getter...
