What is the Moon Phase & Next Full Moon?
The moon phase tool shows the phase, percentage illuminated and the moon's age (days since the last new moon) for today or any date. It also gives the dates of the next new moon and full moon.
Islamic months start after the new crescent is sighted, a day or two after the astronomical new moon. For today's Islamic date see Islamic Date Today (Hijri Converter); for the start of Ramadan see Days Until Ramadan.

New moon vs crescent sighting
The astronomical new moon is when the moon is between the Earth and the Sun and cannot be seen. The thin crescent becomes visible about 15–24 hours or more later, depending on the location and weather, which is why Islamic dates can differ between countries.
