Find out what season it is today and how many days until the next season begins. Based on astronomical seasons.

Season Information

How the Season Calculator Works

Our season calculator determines the current season and calculates days until the next season begins. The calculator uses astronomical seasons, which are based on the Earth's position relative to the sun:

  • Astronomical Seasons: Seasons are determined by solstices and equinoxes - the points when the sun is directly above the equator or at its furthest points north or south.
  • Spring Equinox: Spring begins around March 20-21 when day and night are equal length. This marks the start of spring in the Northern Hemisphere.
  • Summer Solstice: Summer begins around June 20-21, the longest day of the year. This is when the sun reaches its highest point in the sky.
  • Autumn Equinox: Autumn begins around September 22-23 when day and night are equal again. This marks the transition to shorter days.
  • Winter Solstice: Winter begins around December 21-22, the shortest day of the year. This is when the sun is at its lowest point.

The calculator accounts for the exact dates of solstices and equinoxes, which can vary slightly each year. It also calculates days until the next season, helping you plan for seasonal changes, weather transitions, and seasonal activities.

🌡️ Weather Preparation

Prepare for seasonal weather changes by knowing when seasons transition. Helps prepare for temperature changes, precipitation patterns, and seasonal weather conditions.

Tips & Best Practices

✓ Understand Astronomical vs Meteorological Seasons

Our calculator uses astronomical seasons (based on solstices/equinoxes). Meteorological seasons start on the first day of months (March, June, September, December) and may differ slightly.

✓ Account for Hemisphere Differences

Remember that seasons are opposite in the Northern and Southern Hemispheres. When it's summer in the north, it's winter in the south, and vice versa.

✓ Plan for Seasonal Transitions

Use the calculator to plan for seasonal transitions. Knowing when seasons change helps prepare for weather changes, wardrobe updates, and seasonal activities.

✓ Consider Regional Variations

While astronomical seasons are universal, actual weather patterns vary by region. Use season calculations as a guide, but consider local climate patterns for specific planning.

Frequently Asked Questions

How are seasons determined?
Seasons are based on astronomical events: Spring starts at the vernal equinox, Summer at the summer solstice, Fall at the autumnal equinox, and Winter at the winter solstice.
Do seasons vary by location?
The astronomical seasons are the same worldwide, but meteorological seasons and weather patterns can vary significantly by geographic location and climate zone.
Why do seasons change dates slightly each year?
The Earth's orbit around the Sun takes about 365.25 days, so the exact timing of equinoxes and solstices shifts slightly each year, typically by a few hours.
What's the difference between astronomical and meteorological seasons?
Astronomical seasons are based on Earth's position relative to the Sun. Meteorological seasons are based on temperature patterns and are used by weather services for consistency.
