+Date example
+============
+
+Working with dates without a time component is a common task in many
+PHP applications. PHP provides a `DateTime` class (and an immutable variant called `DateTimeImmutable`) for working with datetimes, which
+model a specific moment in time, but there is no built-in way of
+dealing with only dates; if you want to, say, compare dates, you'll
+have to be careful to first remove or equalize the time and timezone components of both datetimes.
+
+```php
+$dateA = DateTime::createFromFormat('Y-m-d', '2019-01-01');
+// one second later
+$dateB = DateTime::createFromFormat('Y-m-d', '2019-01-01');
+
+$dateA == $dateB; // true or false, depending on if the assignments occurred on the same system second!!!
+```
+
+With the power of value objects, we have the capability of
+defining a value object class that encapsulates the concept of a Date,
+and provides useful methods for construction and comparison.
+
+```php
+use SolidPhp\ValueObjects\Value\ValueObjectTrait;
+
+final class Date
+{
+    use ValueObjectTrait;
+
+    /** @var DateTimeImmutable */
+    private $dateTime;
+
+    private function __construct(int $year, int $month, int $day) {
+        // we can make sure the internal dateTimes are always the
+        // start of day of the given source DateTimeInterface in the
+        // GMT timezone.
+        $this->dateTime = DateTimeImmutable::createFromFormat(DateTime::ATOM, sprintf('%d-%d-%dT00:00:00+00:00', $year, $month, $day));
+    }
+
+    public static function of($source): self
+    {
+        if ($source instanceof DateTimeInterface) {
+            $matches = [];
+            if (1 === preg_match('/^(\\d{4})-(\\d{2})-(\\d{2})$/', $source->format('Y-m-d'), $matches)) {
+                [, $year, $month, $day] = $matches;
+
+                return self::getInstance((int)$year, (int)$month, (int)$day);
+            }
+        }
+
+        if (is_string($source)) {
+            return self::of(new DateTimeImmutable($source));
+        }
+    }
+
+    // we can add factory methods that create Dates based on other Dates
+    public function add(DateInterval $interval): self
+    {
+        return self::of($this->dateTime->add($interval));
+    }
+
+    // we can use comparison operators on the internal datetime
+    public function compare(Date $date): int
+    {
+        return $this->dateTime <=> $date->dateTime;
+    }
+
+    public function isBefore(Date $date): bool
+    {
+        return $this->compare($date) < 0;
+    }
+
+    public function format(string $format): string
+    {
+        return $this->dateTime->format($format);
+    }
+}
+
+$date = Date::of('2019-01-01');
+$sameDate = Date::of('2019-01-01');
+$otherDate = Date::of('2019-01-02');
+
+$date === $sameDate; // true
+$date === $otherDate; // false
+$date < $otherDate; // true -- this works because PHP compares the internal properties (i.e. the `DateTime`s)
+
+$nextDate = $date->add(new DateInterval('P1D'));
+$nextDate === $otherDate; // true
+
+```
