Counting in your browser timezone…

Spring begins at the March equinox, the moment the sun crosses the celestial equator heading north. In most years that lands on March 19, 20 or 21, and this countdown aims at the calendar date in US Eastern time. It then rolls to the next equinox once that day ends in your browser timezone. Day and night run close to equal length worldwide, which is where the word equinox comes from. Climate agencies use a simpler rule, calling March 1 the first day of spring, so you may see two answers.

FAQ

When is the first day of spring?
The astronomical first day of spring is the March equinox — next on Saturday, March 20, 2027, then Sunday, March 19, 2028. The exact instant shifts by a few hours each year and resets after leap years, so the calendar date moves between the 19th and 21st. We use the US Eastern calendar date and count to the end of that day in your timezone.
Why do meteorologists say spring starts on March 1?
Weather services group whole months to keep seasonal statistics tidy: spring is March through May, summer June through August, and so on. That version never moves, while the equinox does. Neither is wrong; they answer different questions. This page follows the equinox, because that is the date printed on most calendars and shown in search answers.
Is the day really 12 hours long at the equinox?
Almost, but not exactly. Sunrise is measured from the top edge of the sun and the atmosphere bends light over the horizon, so daylight on the equinox runs a few minutes past twelve hours at mid-northern latitudes. The day that truly splits evenly, sometimes called the equilux, falls a few days earlier in spring.
Does spring start on the same day everywhere?
Not quite. The equinox is one instant worldwide, but the calendar date depends on the clock where you stand. A moment late in the evening Eastern is already the next day in Europe and Asia. In the Southern Hemisphere this event marks the start of autumn, and their spring begins in September.
Is this the same as daylight saving time starting?
No. Clocks in most of the United States spring forward on the second Sunday of March, which is usually a week or more before the equinox. Daylight saving time is a legal rule set by Congress; the equinox is astronomy. They often get lumped together in conversation, so check which one you mean before planning around either date.
