Every full moon date and name for 2026.
A quick note on the personal/social tools: the birthday and soulmate calculators are built on a real, calculated moon phase -- but the "meaning" attached to that phase is tradition and pattern-finding, not science. Treat it as a fun starting point, not a verdict.
Why check your moon phase?
Some people track it for gardening or fishing timing, some are curious about the folklore tied to full moons, and a lot of people are here because a "moon phase soulmate" or "birthday moon" trend showed up on their feed and they wanted the real number behind it. Either way, the phase shown above is calculated the same way for everyone: a real astronomical cycle, not a guess. Curious what tonight's phase is traditionally supposed to mean? See what each moon phase represents.
The moon phase shown above is calculated in your browser using a mean synodic month algorithm (29.53058867 days per lunar cycle) anchored to a known reference new moon. This method is checked against real, published full moon timestamps for 2026 and lands within about half a day of the precise astronomical moment -- accurate enough for a daily check, not observatory-grade. See the Full Moon Calendar for exact, independently sourced full moon dates and times.
Common questions
Is the moon phase shown here accurate?
It's calculated using a well-established mean synodic month algorithm, the same basic approach many moon phase tools use. It's accurate to within roughly half a day of the exact astronomical moment, which is checked against real published full moon times for 2026 -- see the Full Moon Calendar page for the sourced dates.
Does the moon actually affect birthdays or compatibility?
There's no scientific evidence that the moon phase at your birth affects your personality or relationships. The birthday and soulmate tools on this site are built on real lunar calculations, but the meanings attached to them are a cultural and social tradition, not a measured science.
How often do full moons happen?
About once every 29.5 days, which is why some years (like 2026) have 13 full moons instead of 12 -- one month ends up with two.
