What This Calculator Does
This tool counts the number of days from any date you choose until the next Super Bowl. The Super Bowl — the championship game of the US National Football League (NFL) — is currently scheduled on the second Sunday of February. (Note: this is a US sporting event, and the date scheduling reflects the NFL's current calendar; in some past seasons the game fell on the first Sunday of February.)
How to Use It
Enter a "from" date using its year, month (1–12), and day (1–31). The calculator defaults to today's date. It first computes the second Sunday of February for that year. If that date has already passed, it automatically rolls forward to the following year's Super Bowl, so you always get a positive countdown.
The Formula Explained
February 1 of the target year is located, and the calculator finds the first Sunday on or after it. Adding seven days gives the second Sunday. The result is converted to milliseconds and compared against your from-date. The difference in milliseconds is divided by 86,400,000 (the number of milliseconds in one day) and rounded up with a ceiling function so a partial day still counts as a full day remaining.
$$\text{Days} = \left\lceil \frac{\text{SuperBowl} - \text{From}}{86400000} \right\rceil$$ $$\text{where}\quad \left\{ \begin{aligned} \text{From} &= \text{date}\left(\text{Year},\ \text{Month},\ \text{Day}\right) \\ \text{SuperBowl} &= \text{2nd Sunday of February} \\ &\quad \text{(this year if upcoming, else next year)} \end{aligned} \right.$$
Worked Example
Suppose today is January 1, 2025. The second Sunday of February 2025 is February 9, 2025. The gap is 39 days (30 days left in January plus 9 days into February). Because the from-date is at midnight and the target is also at midnight, the ceiling leaves the count at exactly 39 days.
$$\text{Days} = \left\lceil \frac{30 + 9}{1} \right\rceil = 39$$FAQ
Is the Super Bowl always the second Sunday of February? In the current NFL scheduling era it is. Historically it has shifted, so always verify the official date for your year.
What if the date has passed this year? The calculator automatically targets next year's game, giving you a forward-looking countdown.
Does it count today as a day? If you enter today's date, today is the starting point (zero) and the count is the full days until game day.
