The **full moon** has long held significance across cultures, influencing everything from spiritual rituals and agricultural cycles to personal reflection and nighttime photography. Whether you're a stargazer, a gardener following lunar planting schedules, or someone preparing for a ceremonial event, knowing the **next full moon** is essential for effective planning. Accurate timing allows you to align your activities with celestial rhythms—ensuring you don’t miss key moments like optimal moonrise visibility or peak brightness. This user-focused guide delivers precise, actionable information, including the **next full moon date and time**, how to track the **upcoming full moon October 2025**, set a **next full moon calendar alert**, and calculate the exact **days until next full moon**. With step-by-step instructions and result-driven tools, you’ll be fully prepared for the next lunar highlight.

To begin, let’s establish the **next full moon date and time** with scientific precision. According to NASA's Astronomical Applications Department and timeanddate.com, the next full moon will occur on **October 17, 2025, at 18:29 UTC** (Coordinated Universal Time). This moment marks the exact alignment of the Sun, Earth, and Moon—when the Moon is directly opposite the Sun in ecliptic longitude.
Because global users operate in different time zones, converting UTC to local time is crucial. Here are a few examples using standard time zone offsets:
You can use free online converters such as WorldTimeBuddy.com or the built-in world clock feature in Google Calendar to adjust automatically based on your location.
Visibility of this full moon will span **North America, Europe, Africa, and western Asia**, where the Moon will be above the horizon during peak illumination. Observers in eastern Asia and Australia may see it just after moonrise on October 18, though it will have technically already passed full phase. For best viewing, check local moonrise and moonset times via apps like Stellarium or NOAA’s Tides & Currents portal.
This **result-driven** approach ensures you’re not guessing—you’re acting on verified, globally synchronized data.
Now that we know the **next full moon date and time**, let’s explore what makes the **upcoming full moon October 2025** unique. Often referred to as the **Harvest Moon**, this title traditionally belongs to the full moon closest to the autumnal equinox (which falls on September 22, 2025). However, because the October 17 full moon is nearer than the September one, it earns the Harvest Moon designation in 2025—a rare shift that happens roughly every three years.
In some Native American traditions, particularly among Algonquin groups, this moon is also called the **Pre-Frost Moon**, signaling cooling temperatures and the first signs of winter approaching. These names reflect seasonal transitions and offer cultural context for those incorporating lunar symbolism into their practices.
From an astronomical standpoint, the **upcoming full moon October 2025** reaches peak illumination for only a brief instant—18:29 UTC—but visually appears “full” for about three days centered on that date. This extended visual window is due to the gradual nature of lunar phases and human perception thresholds.
Additionally, consider the Moon’s position in its orbit:
Tracking these details enhances both observational experiences and planning accuracy—offering truly **actionable** insights for skywatchers and planners alike.
One of the most effective ways to ensure you don’t miss the **next full moon** is to create a **next full moon calendar alert**. Follow this **step-by-step**, user-focused process across major platforms:
For automated tracking, install astronomy-specific apps:
These tools deliver **user-focused** convenience, ensuring you receive timely updates without manual tracking.
If you want to monitor progress toward the event, calculating the **days until next full moon** gives you a dynamic sense of anticipation. As of June 1, 2024, there are **493 days** remaining until October 17, 2025.
Use this simple formula:
Days Remaining = Target Date (October 17, 2025) – Current Date
Most people prefer digital tools for accuracy:
Manual calculation tips:
By leveraging these **accurate timing** methods, you gain a **result-driven** way to measure time leading up to the lunar event.

Staying informed about the **full moon next** requires more than just awareness—it demands action. By following the steps outlined in this guide, you now have **practical guidance** to:
We recommend bookmarking trusted sources like NASA.gov, timeanddate.com, or the U.S. Naval Observatory’s Astronomical Applications page for future reference. These platforms provide regularly updated ephemeris data validated by international observatories.
As you plan ahead—not just for October 2025 but for subsequent full moons in 2026 and beyond—remember that preparation turns fleeting celestial events into meaningful opportunities. Whether for science, spirituality, or celebration, being ready empowers you to make the most of each lunar cycle.
