The same day, it gets to (5)
I believe the answer is:
ditto
'the same' is the definition.
(thesaurus)
'day it gets to' is the wordplay.
'day' becomes 'd'.
'gets' is a charade indicator (letters next to each other).
'd'+'it'+'to'='DITTO'
(Other definitions for ditto that I've seen before include "As given above" , "that which has been said" , "couple of marks" , "Likewise" , "Two small marks indicating the same again" .)
