Case
- Goal
- Parse custom date formats with mandatory referenceDate, detect interval overlaps with boundary exclusivity, and distinguish 24-hour difference from calendar days in date-fns HOW
- Packages
- date-fns 4.4.0
- Environment
- node
- Created
- 2026-08-16T07:05:16Z
Contract
- assert parse without referenceDate produces an Invalid Date with NaN timestamp
- assert parse with referenceDate resolves custom date patterns to valid Date
- assert parse inherits omitted year, month, and day fields from referenceDate
- assert areIntervalsOverlapping is boundary-exclusive by default (inclusive: false)
- assert areIntervalsOverlapping detects abutting intervals when inclusive: true is specified
- assert isWithinInterval includes both start and end boundaries
- assert differenceInDays counts elapsed 24-hour periods rather than calendar transitions
- assert differenceInCalendarDays reflects calendar crossings regardless of elapsed hours
