siirtopäivä

Siirtopäivä, also known as "transfer day" or "transfer window" in English, is a term used in sports, particularly in association football, to refer to the period during which clubs can transfer players between themselves. The term originates from the Finnish language, where "siirto" means "transfer" and "päivä" means "day."

In most football leagues, the transfer window is typically open twice a year. The first window usually opens in the summer, allowing clubs to strengthen their squads before the new season begins. The second window opens in the winter, providing clubs with the opportunity to make changes to their squads during the mid-season break.

During the transfer window, clubs can sign new players, either by purchasing them from other clubs or by signing them on loan. They can also sell players to other clubs or release them from their contracts. The transfer window is a crucial period for clubs, as it allows them to make significant changes to their squads and improve their chances of success in the upcoming season.

The transfer window is governed by the rules and regulations of the relevant football association or league. In some leagues, there are restrictions on the number of players that can be signed or sold during the window. In other leagues, there are no such restrictions, and clubs can make as many transfers as they wish.

The transfer window is an important event in the football calendar, as it allows fans to see which players are moving between clubs and which clubs are making significant changes to their squads. It also provides an opportunity for clubs to make financial gains or losses, depending on the value of the players they sign or sell.
