The ticket concerned has two validity periods: it can be registered for use within 12 months from the day of its purchase, and the 24h validity period is counted from the moment of the first registration, e.g., if you start to use the ticket on November 25, at 13.59, it will be valid until 13.59 of November 26. If the passenger registers the trip on November 26, at 13.30, and the trip continues after 13.59, the passenger has the right to finish the registered trip.
