Rising Moon Sun Calculator
Understanding the movement of the Sun and Moon has fascinated humanity for thousands of years. Whether you're planning photography, stargazing, outdoor activities, travel, or religious observances, knowing the exact sunrise, sunset, moonrise, moonset, and moon phase can make all the difference.
Our Rising Moon Sun Calculator is a powerful, easy-to-use online tool that calculates:
- Sunrise time
- Solar noon
- Sunset time
- Total daylight duration
- Moonrise time
- Moonset time
- Current moon phase
- Moon illumination percentage
All you need is your latitude, longitude, date, and timezone offset.
What Is a Rising Moon Sun Calculator?
A Rising Moon Sun Calculator is an astronomical tool that determines the daily position and timing of the Sun and Moon for a specific location on Earth.
Using astronomical formulas based on Julian dates and orbital mechanics, the calculator estimates:
- When the Sun crosses the horizon (sunrise & sunset)
- When the Moon appears and disappears
- The percentage of the Moon illuminated
- The current lunar phase
It works for any location worldwide — from the equator to polar regions.
Why Sunrise & Moon Times Matter
Sun and Moon timing data is useful for:
- Photographers (golden hour & blue hour planning)
- Astronomers and stargazers
- Outdoor event planners
- Hikers and campers
- Sailors and fishermen
- Religious observances
- Farmers and agricultural planners
- Travelers exploring new cities
For example, if you're in New York City, sunrise time differs significantly compared to Los Angeles due to latitude and timezone differences.
What This Calculator Computes
🌅 Sun Times
1. Sunrise
The moment the upper edge of the Sun becomes visible above the horizon.
2. Solar Noon
The time when the Sun reaches its highest point in the sky.
3. Sunset
The moment the Sun disappears below the horizon.
4. Daylight Duration
Total hours and minutes between sunrise and sunset.
🌙 Moon Times
1. Moonrise
When the Moon rises above the horizon.
2. Moonset
When the Moon drops below the horizon.
3. Moon Phase
Identifies the current lunar phase, such as:
- New Moon
- First Quarter
- Full Moon
- Last Quarter
4. Moon Illumination
Percentage of the Moon’s surface illuminated by sunlight.
How to Use the Rising Moon Sun Calculator (Step-by-Step)
Using this tool is simple and takes less than a minute.
Step 1: Enter Latitude
Input your location’s latitude (between -90° and 90°).
Example:
- 40.7128 for New York
- 34.0522 for Los Angeles
Step 2: Enter Longitude
Input longitude (between -180° and 180°).
Example:
- -74.0060 for NYC
- -118.2437 for LA
Step 3: Select Date
Choose the date for which you want astronomical data.
Step 4: Enter Timezone Offset
Input hours from UTC (for example, -5 for Eastern Time during standard time).
The calculator auto-fills today’s date and your timezone offset by default.
Step 5: Click “Calculate”
The results instantly display:
- Sunrise
- Solar Noon
- Sunset
- Daylight Duration
- Moonrise
- Moonset
- Moon Phase
- Moon Illumination
Click Reset to start over.
Example Calculation
Let’s walk through a sample scenario.
Location:
New York City
Latitude: 40.7128
Longitude: -74.0060
Timezone: -5
Date:
June 21 (Summer Solstice)
On this date, daylight duration is near its maximum for the Northern Hemisphere.
Typical results would show:
- Early sunrise
- Late sunset
- Long daylight duration (over 15 hours)
- Moon phase depending on lunar cycle
In contrast, on December 21 (Winter Solstice), daylight would be much shorter.
How Moon Phases Work
The Moon orbits Earth approximately every 29.5 days. This cycle is called a synodic month.
The calculator identifies phases such as:
- 🌑 New Moon (0% illumination)
- 🌓 First Quarter (~50%)
- 🌕 Full Moon (~100%)
- 🌗 Last Quarter (~50%)
Moon illumination is calculated using trigonometric functions based on lunar age.
Special Cases: Polar Regions
In high-latitude areas like Reykjavik, sunrise and sunset may not occur daily during extreme seasons.
The calculator accounts for:
- No sunrise (Polar Night)
- No sunset (Midnight Sun)
- 24-hour daylight
- 0-hour daylight
This makes it globally reliable.
