In general, if you bought a ticket for 60 TAT trips (trolleybus, bus, tram), and started using it, then it will finish working in exactly 30 days.
If you happen to have 10-25 trips left, and the ticket expires the day after tomorrow, you can save these trips. The ticket must be “broken” - demagnetize, go to the kiosk where tickets are sold and report that it is not working. You will be given a lot of new tickets: I had 29 trips, they gave me twenty, five and four times one trip).
Received tickets you can use within 1-4 months (depending on the beginning or end of the quarter, you will exchange them) ')
PS I didn't do it on purpose, just the ticket broke. PPS Thanks for the invite!
