College football’s season opener has a strange name: Week 0. The label exists because of a scheduling collision — a handful of games are played the Saturday before the sport’s designated Week 1, and rather than renumber the entire season, everyone simply counted backward. The week before one is zero. What began as broadcast-schedule shorthand became the official-unofficial name of an entire mini-slate, complete with its own traditions.
The games exist because of exemptions, and the name exists because of them too. NCAA rules define a 12-game regular season inside a set calendar window, but teams playing at Hawai’i may schedule a 13th game, and certain neutral-site kickoff classics received waivers to play early. Those extra and early games needed a home on the calendar before Week 1 — and ‘Week 0’ stuck because it was both accurate and funny. There is no Week 0 in the rulebook; there is one on every TV schedule.
The chart below covers where the name came from, the exemptions that create the games, and why 2026’s edition is the last. Take a look, then we’ll get into the naming logic.

Why Is It Called Week 0 in College Football?
The week before Week 1 needed a number — and zero was sitting right there

The name, explained
How zero became a week
| The name |
Explanation |
| Why ‘zero’ |
The season’s numbering anchors to a designated Week 1 (Labor Day weekend); games played the prior Saturday needed a lower number — zero |
| Who coined it |
No single author — TV listings, schedule databases, and media adopted it organically in the mid-2010s as early games multiplied |
| Is it official? |
No — the NCAA calendar doesn’t name it; networks, schools, and fans made it standard anyway |
| Alternatives that lost |
‘Kickoff Weekend’ and ‘Week One-A’ never took; zero was cleaner |
| The comedy of it |
A week numbered zero implies the season starts before it starts — which is precisely the joke and precisely the fact |
The exemptions behind the games
Why anyone plays early at all
| Exemption |
How it creates Week 0 games |
| The Hawaii rule |
Teams playing at Hawai’i in a season may schedule a 13th game; the extra game needs an extra week — and Hawai’i itself opens early most years |
| Kickoff classics |
Neutral-site season openers (most famously the Aer Lingus Classic in Dublin) received waivers to play the early Saturday |
| FCS and international slates |
Lower-division openers and showcase games (MEAC/SWAC Challenge) fill out the weekend under related exemptions |
| The waiver process |
Schools petitioned the NCAA for early-start permission case by case — which is exactly the process the NCAA has now ended |
A brief history of Week 0
From quirk to institution to sunset
| Week 0’s short history |
Milestone |
| Pre-2016 |
Occasional early games existed (Hawai’i openers, one-off classics) without a collective name |
| 2016-2019 |
The slate grows; ‘Week 0’ becomes standard media usage |
| 2022-2025 |
Dublin’s Aer Lingus Classic makes Week 0 an institution with an international flagship |
| 2026 |
The final Week 0: Aug. 27-30, headlined by UNC-TCU in Dublin |
| 2027 |
The NCAA’s standardized 14-week season absorbs the early games into a uniform calendar — Week 0 waivers ended |
WEEK 0 FACTS
Zero-indexing, accidentally
Programmers found the name delightful — college football adopted zero-based numbering the way software does, purely by scheduling necessity.
The games always counted
Despite the name, every Week 0 game is a full regular-season contest — zero refers to the calendar slot, not the stakes.
The name outlives the week
Even after 2027’s standardization, expect ‘Week 0’ to linger as shorthand for opening-weekend appetizer games — names this good don’t die on schedule.
The Naming Logic, Fully Unpacked
Sports seasons are numbered from their traditional start, and college football’s traditional start is Labor Day weekend — Week 1 by long convention, locked in by TV contracts, ticket packages, and a century of habit. When exempted games crept earlier, the sport faced a choice: renumber everything (making Dublin ‘Week 1’ and shifting fourteen weeks of references), or extend the number line downward. The path of least resistance won, as it always does, and the season gained a prologue week whose very name admits it shouldn’t quite exist. It’s the rare piece of sports terminology that is simultaneously informal, universal, and mathematically correct.
The Bottom Line
It’s called Week 0 because the games fall the Saturday before the sport’s anchored Week 1, and counting backward from one lands on zero — an unofficial name made universal by TV schedules and the exemptions (the Hawaii rule, kickoff-classic waivers) that created the early slate. The 2026 edition is the last before the calendar standardizes. For this year’s full early slate, see the 2026 Week 0 schedule, and for the main event a week later, the Week 1 schedule and TV guide.
