Common Issues & Fixes
Issue: The day count seems off by one.
Fix: Date difference calculations can be inclusive or exclusive. This tool counts the days between the dates (exclusive of the start date). If you need inclusive counting, add 1 to the result.
Issue: The month calculation does not seem right.
Fix: Months have different lengths (28-31 days), so "1 month" is not always 30 days. The tool calculates calendar months, which is the standard approach.
