Available nights
Available nights: Nights on a listing's calendar that a guest could book on the day we looked.
How we measure it
We count open nights in the first 30, 60, 90 and 365 days of the calendar, starting from the first day of the observation month.
What it is not
Few available nights does not prove high demand: a host may have blocked the calendar, and nights already past in the month count as unavailable, so late in a month the 30-day count covers only the nights left.
Where it appears in the data
