date_duration

verifiedv0.1

Calculates days, weeks, months and optional business days between two calendar dates in the browser. Pass start and end as ISO yyyy-mm-dd (exactly 10 chars) plus optional inclusive and businessDays. Variant URLs are not a second machine Tool — pass inclusive and focus explicitly. Do not use this to add or subtract a duration from one date (that is date_add_subtract).
