Frequently Asked Questions

How accurate are these astronomical event dates?
Solstice and equinox dates are calculated from JPL DE440 ephemeris data (the same planetary/lunar ephemeris used by NASA). Meteor shower peak dates follow the International Meteor Organization (IMO) annual calendar. All dates are in UTC.
Can I observe meteor showers from my location?
Meteor showers are visible worldwide, but the radiant altitude affects hourly rates. Use FastTool's Sidereal Time Calculator to plan when the radiant is highest at your longitude. The darkest hours after astronomical twilight are ideal — use our Twilight Calculator to find your window.
What is the difference between a solstice and an equinox?
A solstice occurs when the Sun reaches its northernmost (+23.44°) or southernmost (−23.44°) declination, giving the longest or shortest day. An equinox occurs when the Sun crosses the celestial equator (0° declination), giving roughly equal day and night worldwide.
Why are the events listed in UTC?
Astronomical events are independent of time zones — UTC is the universal standard. Convert to your local time by adding or subtracting your UTC offset. For example, Eastern Daylight Time (EDT) is UTC−4.
