System Objective
Accurate day counting is essential for SLA tracking, contract term validation, and proration logic. This tool standardizes calculation methods to prevent "off-by-one" errors common in ad-hoc spreadsheet math.
Finance Logic
The calculation uses strict start-of-day timestamps (00:00:00) to ensure whole-day integers, independent of timezones or seconds.
Total Days = (End Date - Start Date)
Term in Years
Calculates the precise decimal year value based on a standard 365-day year basis (Actual/365).
Total Days / 365.0000
