Date & Time Elapsed
Elapsed time between two date-and-time-stamps in days, hours and minutes.
About Date & Time Elapsed
Each date is converted to its total minutes since an epoch, so subtracting the start from the end reveals the whole elapsed span. Precise elapsed time is essential for billing, logging and understanding how long an activity actually takes.
Formula
Date & Time Elapsed
Elapsed minutes = (end days x 1440 + end clock) - (start days x 1440 + start clock)
- clock
- Hours and minutes converted to minutes of the day

Assumptions and limits
- The result is derived only from the 10 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
