Anime Seasons Explained: Winter, Spring, Summer and Fall

Anime is released in broadcast seasons. Knowing how the calendar works makes it easier to follow new releases and to understand terms such as "cour" or "split cour."

The four seasons

Each season lasts roughly three months. Shows that begin in a season are called "that season's anime", even if they finish later.

What is a cour?

A cour is one block of roughly twelve or thirteen episodes, equal to a season of broadcasting. A show planned for two cours has about twenty-four episodes. Some series use a split cour, airing one cour, pausing for a season or more, and then continuing.

Continuing vs. new shows

Alongside brand-new titles, each season includes shows that started earlier and are still running, often described as "carry-over." Long-running series can remain on air for years, and a new season of a popular series is generally announced in advance by its studio.

Donghua calendars

Chinese animation is less tied to those four blocks. Many series are released weekly all year, and seasons are sometimes numbered by the story rather than the calendar. It is useful to check each series' official announcement channel for its schedule.

How to use the calendar

1. At the start of a season, read the list of new titles.
2. Pick two or three that appeal to you rather than trying to watch everything.
3. Check which are on your legal streaming service.
4. Add them to your watchlist and set a day of the week to watch.

Limiting yourself to a few shows each season keeps viewing relaxing and helps you avoid the guilt of a long backlog.

Why the system exists

The seasonal system comes from how Japanese television schedules programmes. Broadcasters organise their late-night and daytime slots in quarterly blocks so that advertisers and production teams can plan ahead. Even though streaming has made watching more flexible, the seasonal rhythm remains the standard way to talk about new releases.

What a typical season looks like

A season usually has dozens of new series, ranging from big adaptations of popular manga to original stories. Some are sequels to earlier seasons. Most of the conversation online centres on a handful of standout titles, but there are often hidden gems that receive less attention. Reading a few first impressions, then testing the first episode, is the best way to find them.

Premiere week habits

• Create a short list of "must try" shows and a second list of "maybe."
• Watch the first episode of each in a single weekend.
• Drop anything that doesn't hold your interest and keep three or four to follow weekly.

Simulcasts and delays

Many streaming services release new episodes shortly after the original broadcast. In some regions there may be a delay, and dubbed versions often arrive later than subtitled ones. Checking the release schedule on the platform can save confusion.

Mid-season and end-of-season

Around the middle of a season, you will see announcements about sequels and film adaptations. At the end, many series finish, others pause as a split cour, and some continue directly into the next period. When a series ends on a cliffhanger, it usually means a sequel is planned, though timing can vary. Patience is part of the fandom experience.
