aikaväleiden
Aikaväleiden, the Finnish term for time intervals, refer to the span of time between two moments. In mathematics, a time interval is described by a start time t0 and an end time t1, with t1 ≥ t0; the duration is Δt = t1 − t0, measured in units such as seconds, minutes, or hours. Intervals can be closed [t0, t1], open (t0, t1), or half-open [t0, t1), depending on whether the endpoints are included. In continuous-time analysis, these intervals define the periods over which a function is observed or a process operates.
In data analysis, the term often concerns the times between events, known as inter-arrival times. These intervals
Applications include scheduling and project timing, where aikaväleiden determine task durations and deadlines; time series analysis,
Standard representations such as ISO 8601 help ensure consistency when exchanging interval data across systems, using
