Monthly short-stay projection

Scenario for one unit available every calendar day. With 24 consecutive months: additive Holt-Winters; with 6–23 months: constant mean. History length does not establish reliability.

Historical revenue uses reported sold nights × ADR; without nights, it is estimated as occupancy × actual calendar days × ADR. Zero nights remain zero. Forecast revenue uses occupancy × calendar days × ADR. These are gross accommodation receipts before costs, commissions and taxes. Do not combine multiple units or partial availability in this model.
