Season Today Calculator
Enter a date and choose the hemisphere to know whether it is spring, summer, autumn or winter.
What this tool does
The Season Today calculator uses common astronomical equinox and solstice dates to estimate the current season. It helps with quick checks, calendars, educational content and seasonal writing.
Because seasons are opposite across hemispheres, the page lets you switch between northern and southern hemisphere. Dates may vary slightly by year and astronomical source.
