põhiaeg
Põhiaeg is an Estonian term that generally translates to "main time" or "primary time." It is most commonly used in the context of scheduling or planning, referring to the core or most important period allocated for a particular activity or event. For example, in project management, põhiaeg might denote the central phase of a project, distinct from preparatory or concluding stages. In a daily schedule, it could represent the primary block of time dedicated to work or a specific task. The concept emphasizes the essential duration rather than ancillary or peripheral timeframes.
The term's application is flexible and depends heavily on the specific context in which it is used.
