About RSDateSpan

Measure a date span in whole calendar days. Choose whether to count both endpoints, and see the corresponding weeks and remaining days.

A focused workflow

October 1 to October 4 is a three-day difference. Counting both calendar dates inclusively gives four days.

The site is designed around one specific task: date difference calculator. The workspace is accompanied by instructions, worked examples and guides explaining the limits of the result. It does not claim to replace a professional print, document-security or deadline-review workflow.
