How Many Days Until Summer?

Calculating...

How It Works

This tool automatically calculates and displays the number of days remaining until the start of summer (June 21st in the Northern Hemisphere). The countdown updates every second and adjusts for the current year or next year's summer depending on today's date.

Meet the Countdown Tool

This tool shows the time left until summer. It updates every second. You can see days, hours, minutes, and seconds.

Understanding the Inputs

You see two radio buttons on the page. One is for the northern hemisphere and one is for the southern hemisphere. Pick the one that fits your location.

Interpreting the Output

The main display shows how many days remain until summer. You also see extra details on hours, minutes, and seconds left.

If the countdown shows zero days, it means summer starts today. The tool also shows the exact start date.
