Make Airbnb calendar
exports great again

Just modify the query as you need: https://bnbcal.now.sh/api/ical.js?timezone=America/New_York&checkout=10&checkin=14&fromURL=https://bnbcal.now.sh/example.ics >> Example <<
Airbnb calendar exports don't reflect the actual guest check-in and check-out times and it breeds confusion. This tool fixes it. With this API, you can generate a more useful ics URL (ex: so the cleaner knows what time they can show up). Then you can import the URL into Google calendar or similar.

timezone: The TZID (timezone) for the listing (ex: America/New_York)
checkout: The hour guests must checkout (ex: 10 = 10:00 AM)
checkin: The hour guests may checkin (ex: 14 = 2:00 PM)
fromURL: The iCal/.ics link from Airbnb (ex: https://www.airbnb.com/calendar/ical/123.ics?s=456)
