Convert Gregorian calendar date to Jalali

$date = new Jalali();
echo $date->setGregorianDate(new \DateTime())->getJalali()->format('Y/m/d');

As you may have noticed, you can use PHP's standard date format characters to format your Jalali date. Isn't that cool?

Convert Jalali calendar date to Gregorian

$date = new Jalali(1392, 6, 6);
echo $date->getGregorian()->format('Y/m/d');

Formatting the converted date

Let's say you want to output the Jalali converted date to something like "پنج شنبه، ۸ شهریور ۱۳۹۲" You can achieve this by

$date = new Jalali();
echo $date->setGregorianDate(new \DateTime())->getJalali()->format('w, d F Y');

This looks pretty much like the above code. All I have done is that I have provided a different format string w, d F Y

Adding units of date/time to the Jalali calendar date

To add a number of years/months/days/hours/minutes/seconds to the converted Jalali date you can use the add() method.

This method accepts two arguments. The first one is the number of units to add to the date and the second one is the date/time designator character.

Let's say you want to add 7 days to the current date.

$date = new Jalali(1392, 6, 6);
echo $date->add(7, 'D')->format('Y/m/d');

You could also do it like this:

$date = new Jalali(1392, 6, 6);
echo $date->add(1, 'W')->format('Y/m/d');

Again if you've noticed, PHP's standard DateInterval characters are used to add units of date/time to the Jalali date.

You can also use negative values for the unit being added to the Jalali date to subtract the amount of date/time from the Jalali date if you need to navigate backward in time.

Convert TIMESTAMP to a Jalali calendar date

$date = new Jalali();
echo $date->setTimestamp(time())->getJalali()->format('Y/m/d');

It was that simple. All you need to do to convert a timestamp.
