“How many days until Columbus Day?” — quick FAQ
Which rule does this page use?
We follow the U.S. federal holiday rule: the second Monday in October is Columbus Day.
Why does your headline match other countdown sites?
The headline shows calendar days — a midnight-to-midnight comparison that includes today. It updates once per day at your local midnight, so it won’t bounce during the day.
What do the hours/minutes/seconds represent?
The live ticker counts to your local 00:00 at the start of the holiday. Those values come from a precise millisecond difference, while the day count uses calendar math. Together they stay intuitive and consistent.
Does daylight-saving time change the result?
No. The day count is tied to calendar dates, not clock hours. Whether a day has 23, 24, or 25 hours around a DST change, the calendar-day number remains correct. The live clock always targets your local start of the holiday.
Can I copy the date cleanly?
Yes — use the copy buttons to grab either the long English date or the ISO 8601 format (YYYY-MM-DD) for forms, spreadsheets, and filenames.
How this page calculates the Columbus Day countdown
This page provides two complementary views of time until Columbus Day. The large grey box shows a calendar-day count — the number of date boundaries between today and the holiday, computed midnight-to-midnight and including today. That keeps the headline steady during the day and mirrors how most people mark off wall calendars.
Beneath it is a real-time breakdown in hours, minutes, and seconds to your local 00:00 at the start of the holiday. By separating calendar logic (days) from clock logic (hours/minutes/seconds), the display avoids distracting mid-day oscillations while still providing a precise ticking target for travel and planning.
To compute the date each year, we find the second Monday in October: take October 1, locate the first Monday, then add one week. If your device is already at or past the start of that Monday, the countdown automatically advances to the next year so it never sits at zero all day.
For coordination, we include useful metadata — the target date’s day-of-year index and ISO week number — plus common numeric date formats. Everything runs locally in your browser; no time-zone or location data is sent anywhere. The mini calendar opens on October and highlights the correct Monday, with arrows to browse adjacent months.
