Answer

"it's not too late"-> " non è troppo tardi"
Tardo is not the singular of Tardi  
Tardi è un avverbio, Tardo è un aggettivo

tardi= in ritardo -> "LATE"
tardo-> slow (person),for historical periods

example...
 Mi sono svegliata tardi = i wake up late
il treno è arrivato in ritardo = the train has arrived late
 tu sei tardo di riflessi!
tardo medioevo = the late Middle Ages
