Based on names this is translated from Romanian

"Early bird alarm clock" has it under the repeat menu you can set a date/dates for alarms.

I like most the voting one, the astronaut(?), and the self referential one. Great job!

I use Passandroid but is quite old https://f-droid.org/packages/org.ligi.passandroid

Sorry, looked for it but I guess it is not open source :( I tried many apps and this one was the only one I found with a date alarm schedulde. weird how such a basic feature is so rare. Maybe try some tasks apps that have alarms? Please let us know if you find something useful

Butt all are nice 😁
