What the result means
The calculator compares two selected dates and returns the span in several time units. Days are the clearest unit for exact calendar gaps; weeks and months help when you are explaining a longer period.
Example
Compare the first and last day of a school term, trip, contract or project. Then use the weekly result to estimate how many review points, payments or check-ins fit inside the span.
Common mistake
Do not use the approximate months row for legal or billing deadlines unless the rule specifically allows averages. Use the exact dates and days for formal deadlines.
