string->date only fails with "bad day"

[Efimero]

I need to parse some dates, so I imported SRFI-19
When trying to use it it errored with bad day, so I looked at the format
It kept saying bad day, so I started testing... and uhh...
Am I doing something wrong?

stklos> (string->date (date->string (current-date) "~5") "~5")
**** Error:
check: bad day #f
stklos> (string->date (date->string (current-date) "~1") "~1")
**** Error:
check: bad day #f
	(type ",help" for more information)
stklos> (string->date (date->string (current-date) "~2") "~2")
**** Error:
check: bad day #f
	(type ",help" for more information)
stklos> (string->date (date->string (current-date) "~Y") "~Y")
**** Error:

stklos> (string->date (date->string (current-date) "~s") "~s")

I confirm this -- it happens with the latest git checkout.

Something in SRFI 19 isn't working properly...

I confirm too 😢.
I'll take a look at it.
