+return $dt->format('Y-n-j H:i'); // 1395-10-7 14:12
+return $dt->format('%B %d، %Y'); // دی 07، 1395
+return $dt; //1395-10-07 14:12:32
+
+// use predefined format
+$dt = new Verta();
+return $dt->format('datetime'); // 1395-12-10 23:25:12
+return $dt->format('date'); // 1395-12-10
+return $dt->format('time'); // 23:26:35
+
+// use predefined format method
+$dt = new Verta();
+return $dt->formatDatetime(); // 1395-12-10 23:37:26
+return $dt->formatDate(); // 1395-12-10
+return $dt->formatTime(); // 23:26:35
+return $dt->formatJalaliDatetime(); // 1395/12/10 23:46:09
+return $dt->formatJalaliDate(); // 1395/12/10
+
+// get gregorain datetime
+return $dt->DateTime()->format('Y-m-d H:i:s'); // 2017-05-23 23:21:02
+return $dt->formatGregorian('Y-m-d H:i:s'); // 2017-05-23 23:21:02
+
+// set default format
+Verta::setStringformat('Y/n/j H:i:s');
+return new Verta(); // 1395/12/12 00:11:35
+
+// reset default format
+Verta::resetStringFormat();
+return new Verta(); // 1395-12-12 00:18:04
+
+// change english number to persian
+$dt = Verta::parse('1396-10-07 14:12:32');
+return Verta::persianNumbers($dt); // ۱۳۹۶-۱۰-۰۷ ۱۴:۱۲:۳۲
+```

+#### Comparisons
+```php
+// is leap year 
+echo Verta::isLeapYear(1394); // false
+echo Verta::isLeapYear(1395); // true
+
+// is valid date
+echo Verta::isValideDate(1394, 12, 30); // false
+echo Verta::isValideDate(1395, 12, 30); // true
+
+// is valid time
+echo Verta::isValideTime(15, 62, 50); // false
+echo Verta::isValideTime(15, 12, 30); // true
+
+// get a diffrent time with now
+$dt = Verta::parse('1395-10-07 14:12:32');
+return $dt->diffNow(); // 2 ماه پیش
+
+$dt = Verta::parse('1395/12/12 14:13:50');
+return $dt->diffNow(); // 5 ثانیه بعد
+```
+

+#### Transformations
+```php
+// get jalali a gregorian date
+return Verta::getJalali(2015,12,25); // [1394,10,4]
+
+// get gregorian a jalali date
+return Verta::getGregorian(1394,10,4); // [2015,12,25]
+
+// export to datetime object
+$dt = Verta::parse('1395/01/05 23:50:25');
+$dt = $v->DateTime();
+
+// export to carbon object
+$dt = Verta::parse('1395/01/05 23:50:25');
+$c = Carbon::instance($v->DateTime());
