I'm not sure what you're on about but you'll have to start and stop development exactly within the time that's displayed on Itch.io for Kenney Jam, it doesn't work any other way. If you submit your game past the deadline you unfortunately won't be able to participate.

FWIW, TL;DR: The jam countdown was longer than 48 hours (went from “2023-07-21 10:00:00 UTC” to “2023-07-23 15:00:00 UTC”), i.e. 53 hours.
I assumed the duration being longer than 48 hours was intentional and thus confused the jam with a different jam which does have a longer duration intentionally for the reasons originally described.
Thanks for running the jam, the assets & your other contributions to the community. :)
