The astronomy dashboard combines solar data, lunar data, and seasonal information into a single view. Instead of checking separate tools for sunrise, moon phase, and season, you get everything in one place for planning outdoor activities, photography sessions, or astronomical observations.
Astronomy enthusiasts use the dashboard to plan observation nights. On July 18, 2026 in New York, the dashboard shows a waxing crescent moon (18% illuminated, setting around 11:20pm), which means the sky will be reasonably dark after moonset for deep-sky observation. The next new moon on July 20, 2026 offers the darkest skies.
Event planners use the dashboard to check sunset and moonrise times for outdoor evening events. A beach wedding in Santorini on September 12, 2026 needs to know that sunset is around 7:30pm and a nearly full moon rises at 7:45pm, providing natural lighting for the reception.
Farmers and gardeners consult seasonal data alongside solar information to plan planting and harvesting. Knowing the exact day length and solar noon helps with irrigation scheduling and greenhouse management.
Educators use the dashboard as a teaching tool, showing students how solar and lunar cycles interact and how seasons change with the Earth's orbital position.
The dashboard pulls data from three calculation systems. Solar data (sunrise, sunset, solar noon, twilight times) comes from the suncalc library's solar position algorithm. Lunar data (phase, illumination, distance, moonrise, moonset) comes from suncalc's lunar position algorithms. Seasonal data is calculated from the Earth's orbital position relative to equinox and solstice dates.
Solar noon is the moment when the sun reaches its highest point in the sky, which is not necessarily 12:00pm local time. The difference depends on your longitude within your timezone and the equation of time, a seasonal variation caused by Earth's elliptical orbit and axial tilt.
Day length is calculated as the time between sunrise and sunset. The dashboard also shows twilight periods (civil, nautical, astronomical) for a complete picture of available light.
Season information is based on equinox and solstice dates for the selected year. In the northern hemisphere, summer solstice (around June 20-21) is the longest day, and winter solstice (around December 21-22) is the shortest. The seasons are reversed in the southern hemisphere.

Things to be aware of
What data does the astronomy dashboard show?
The dashboard displays solar data (sunrise, sunset, solar noon, day length, twilight times), lunar data (moon phase, illumination, distance, moonrise, moonset, next full and new moon), current season, and upcoming astronomical events. All data is calculated for your selected location and date.
How is solar noon different from 12:00pm?
Solar noon is when the sun reaches its highest point in the sky. Clock noon (12:00pm) is based on your timezone, which averages solar time across a 15-degree band of longitude. Your actual solar noon may be earlier or later than 12:00pm by up to 30 minutes, depending on where you are within your timezone.
Can I see data for a past or future date?
Yes. Select any date and the dashboard calculates solar and lunar positions for that date. Past dates use historical astronomical data, and future dates are predicted based on orbital mechanics. Both are accurate for the geometric positions of the sun and moon.
Why does the moon sometimes rise during the day?
The moon is visible during daylight hours for most of each month. Since moonrise advances by about 50 minutes per day, the moon rises at various times throughout the day and night over a lunar cycle. Only during a full moon does it rise approximately at sunset.
What are the upcoming astronomical events?
The dashboard lists the next full moon, new moon, and season change (equinox or solstice). These are calculated based on lunar orbital periods and the Earth's position in its orbit around the sun.
How is the season determined?
Seasons are based on equinox and solstice dates. In the northern hemisphere: spring equinox (March), summer solstice (June), autumn equinox (September), winter solstice (December). The southern hemisphere seasons are reversed.
Why does day length vary so much at different latitudes?
Day length variation is caused by Earth's 23.5-degree axial tilt. At the equator, day length is nearly constant at about 12 hours year-round. At higher latitudes, the tilt causes dramatic variation: from 24 hours of daylight in polar summer to 24 hours of darkness in polar winter.
Is the astronomy dashboard accurate enough for scientific use?
The dashboard uses well-established algorithms (suncalc, based on NREL and Jean Meeus standards) and is accurate for general purposes. For professional astronomy, satellite tracking, or navigation, use dedicated scientific software with higher-precision algorithms.
Astronomical calculations are based on well-established algorithms and are accurate for general planning and educational purposes. Solar and lunar positions are typically accurate within 1-2 minutes for rise/set times and within 1% for illumination. For professional astronomy or navigation, use dedicated high-precision tools.
