How it works
The tool compares two calendar dates without applying country-specific holidays. It is the cleanest starting point when you need to reason about duration before moving into business-day rules.
Example use case
Compare a contract term, notice period or project window in plain calendar terms first, then continue into the working-day tools if operational capacity matters.
