Days And Months I Sing

Thirty days has September
 April. June and November
 I sing the lines with felicity 
the rhyme  I learnt in December
years back taught by the faculty
those of whom now rest in slumber.

One more  technique  holds sway
 tapping on the knuckles as if in a play
the months which fall on the high ridges
will  have thirty one  days.
 the rest which come in the bridges 
stay  satisfied with thirty in the fray.

Forgot February that lies condensed  to twenty eight 
granted  one day every fourth year to set it right.
