The argument i.24 to fmthours may be unnecessary.
In any case, you can generate all hours as:
allhours=: , (;:'am pm') (,~":) each/ _1|.1+i.12
Then fmthours is:
fmthours=: {&allhours
For example;
fmthours 4
+---+
|4am|
+---+
fmthours i.24
+----+---+---+---+...
|12am|1am|2am|3am|...
+----+---+---+---+...
