Description
Parse real YYYY-MM-DD arrival and departure dates at UTC midnight, require departure no earlier, and divide their difference by 86400000 for nightCount.
Travel dates, ticket changes, and service windows combine calendar labels with operational rules. A date calculation can check supplied boundaries, but it does not establish availability, eligibility, or a provider's current policy.

}Limitations and assumptions
- This counts calendar nights from named dates rather than elapsed hours, lodging use, or a timezone-aware journey.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
