# List the dates with trains

GET https://api.sar.worldticket.cloud/sms-gateway-service/schedule/calendar/availability

List the dates inside a window that have at least one train on a route. Built for a date picker: grey out the days missing from `dates`. A date in the list means a train runs that day; it does not promise seats or a price, so search for the day the traveler picks.
