“How many days until spring?” — quick FAQ
Which “spring” does this page track?
This page tracks the astronomical start of spring in the Northern Hemisphere, anchored to the March equinox. For simplicity and consistency, we treat spring as beginning near March 20, and always roll forward to the next upcoming start date.
Is this based on the equinox or a fixed date?
The countdown is equinox-based but implemented using a stable March 20 rule that matches modern patterns in most locations. Actual equinox times can shift slightly; this tool provides a clear, reusable planning date instead of minute-by-minute astronomy.
Why use calendar days in the headline?
The big number uses calendar days, counting midnight-to-midnight and including today. That keeps the result stable and easy to share for launches, events, and campaigns.
What can I plan with this countdown?
Use it to schedule garden prep, trips, retail switches, content campaigns, school terms, sports, and outdoor events without manual date math.
Does this respect my time zone?
Yes. All calculations run entirely in your browser using your device time; no time-zone or location data is transmitted.
How do I copy the spring start date?
Use the buttons beneath the result: one copies the full written date, the other copies the
ISO 8601 format (YYYY-MM-DD) for calendars and documentation.
How this page calculates the Spring countdown
This tool is built to answer one seasonal question cleanly: how many days remain until the start of spring? Instead of hard-coding years, it uses a simple rule tied to the March equinox so the page updates itself for you.
When you load the page, a lightweight script reads your current local date and time directly from your device. It sets a target at March 20 of the current year—the standardized spring start used here to mirror the equinox for the Northern Hemisphere. If your local time is already at or past that date’s midnight, the target automatically jumps to March 20 of the following year so the countdown always points forward.
The bold figure in the grey box uses a calendar-day method. It counts the number of midnight boundaries between “today” and the target spring start, with today included. That matches how most people mark days on a wall calendar and prevents the headline from wobbling as hours pass.
Beneath that, a live breakdown converts the remaining time into hours, minutes, and seconds until your local midnight at the start of spring. This dual view keeps the main answer simple (“X days left”) while giving marketers, planners, and travelers the precision they need for launches, bookings, and campaigns.
For unambiguous communication, the page prints the target date in multiple numeric formats and
also exposes its day-of-year index
plus ISO week number.
Using ISO 8601 (YYYY-MM-DD) avoids mix-ups between local styles when you share
spring timelines across teams and countries.
All countdown logic runs entirely in your browser—no external APIs, no tracking of your time zone—and the inline calendar opens to March with the spring start date highlighted so you can see exactly where the season change lands at a glance.
