Frequently Asked Questions
What moon phase is it today?
The tool above calculates the current Moon phase from the exact Sun-Moon angle for today, then labels the phase and shows illumination.
What sign is the Moon in today?
The same calculation returns the Moon's tropical zodiac sign and degree for the selected date or current moment.
How accurate is the current moon phase tool?
It uses Swiss Ephemeris planetary longitudes for the Sun and Moon, then derives phase angle and illumination from those positions.
Can I check a different date?
Yes. Enter any date in the tool and it recalculates the Moon phase, Moon sign, illumination, and next full moon from that date.
What is moon illumination?
Illumination is the approximate percentage of the Moon's visible disk lit by the Sun from Earth's perspective.
