Hokkaido shinkansen schedule?

hi!

I'm trying to plan a trip to Hokkaido using the seishun kippu and have discovered I won't be able to take the express on Mar 25th due to construction, so I was planning on taking the new shinkansen with the extra cost (still wayyy less than usual train costs or a plane ticket!) on the 26th. however, I can't seem to find the schedule anywhere. even hyperdia doesn't seem to be capable of telling me when it's operating... does anybody know?

thanks!

Here you go:

The purple part is the shinkansen part
奥津軽いまべつ is Oku-Tsugaru Imabetsu
木古内 is Kikonai

From Kikonai to Hakodate, Seishun 18 Kippu users should use the new South Hokkaido Railway (Donan Isaribi Railway); however, their timetable does not seem to have been announced yet.

Hyperdia is unlikely to be updated until mid March.

The first day of the operation of a new train may be almost impossible to get tickets. When the Hokuriku Shinkansen opened, tickets sold out in minutes. I would be very surprised if they don't sell out.
