AHL, explained.Thirty-two farm clubs. One Calder Cup. Here’s the quick guide.
The American Hockey League is the NHL's primary development league: 32 affiliates in four divisions, an NHL-style points race, and a long spring playoff for the Calder Cup.
The AHL was formed in 1936 and has been the NHL's top farm circuit for decades. Every current NHL club has an AHL affiliate.
The championship trophy is the Calder Cup, named for Frank Calder, the NHL's first president. It is not the Memorial Cup (major junior) and not the Kelly Cup (ECHL).
Open a club for that desk’s news and scores.
Same rink rules as the NHL, with call-ups and send-downs all year.
A game is three 20-minute periods of 5-on-5 hockey, with intermissions in between. The team that scores more goals wins.
A win is worth two points. A regulation loss is zero. If the game goes to overtime or a shootout, the loser still gets one point.
Players move between the NHL club and its AHL affiliate. A call-up can happen on a game day; a player sent down lands back on the Calder Cup roster.
A penalty puts the other team a skater up. That extra-man advantage is the power play; the shorthanded side is on the penalty kill.
A player cannot enter the offensive zone ahead of the puck (offside). Icing is shooting the puck the length of the ice from behind centre; play stops and the faceoff comes back.
Atlantic and North in the East; Central and Pacific in the West. Each NHL team has one primary affiliate.
A long regular season into April, then the Calder Cup playoffs into June.
Most of the league qualifies. The last club standing lifts the Calder Cup.
Recent seasons have used a 23-team field — the top finishers in each division, with some first-round byes for division winners. Confirm the 2026–27 grid on the AHL site when it is posted.
Early rounds stay inside the division, then the winners meet in conference finals.
The two conference champions play a best-of-seven final for the Calder Cup.
