8tunnin
8tunnin is a Finnish term used to denote a period of eight hours. The expression is formed from the numeral eight and the noun tunti (hour) and is commonly written in hyphenated form as 8-tunnin when used to modify a noun, for example in phrases describing a workday or a time block. In informal writing, you may encounter variants without a hyphen, but the hyphenated form is standard in most Finnish style guides.
The concept is closely linked to the historical eight-hour day, a principle central to early 20th-century labor
In contemporary usage, 8tunnin appears in time budgeting, scheduling, and duration descriptions, particularly in Finnish-language planning
