The week-by-week countdown to Spring Equinox 2027

- Event date: Saturday, March 20, 2027
Spring Equinox 2027 is 43 weeks and 6 days away, landing on Saturday, March 20, 2027 — that works out to 307 days in total. Spring Equinox is an astronomical event whose exact date and time can be calculated years in advance from precise celestial mechanics. Spring Equinox falls on the weekend this year, which makes it easier to gather without booking time off work.
Counting down turns a vague "soon" into a clear number of days you can plan around — booking travel, sending cards, or simply building anticipation. Many people begin preparing for a date like this two to three months ahead, and a visible countdown helps pace that preparation rather than leaving everything to the final week. If you are counting down to Spring Equinox, you can add a free Outside countdown widget to your iPhone home screen; it updates every day and can be shared with friends and family.

When and How to See Spring Equinox
Astronomical events follow precise, predictable celestial mechanics — the alignment of the Sun, Earth, and Moon, or Earth's position in its orbit. That predictability is what lets Spring Equinox 2027 be calculated to the exact date and time years in advance.
Many of these events reward a little preparation: a clear sky, a dark spot away from city lights, and good timing. Eclipses and meteor showers are visible only from certain regions or at certain hours, so it is worth checking visibility for your location. A countdown ensures you set aside the evening before the moment passes — some of these events will not repeat for years.
