There are 7 timing indicators mentioned in Song of Solomon Chapter 2.
 
ALL 7 obviously apply to just one Season. I know of no other season than Spring that these can apply to.
 
Here they are:
 
From Song of Solomon ch. 2

1) For lo, the winter is past....IF WINTER IS PAST IT MUST BE SPRING......NOT FALL, NOT SUMMER.............DUH?

2) The rain is over and gone. THE LATTER RAINS STOP BEFORE THE PASSOVER, FEAST OF FIRSTFRUITS, WHEN THE HARVEST STARTS. GOD ORDAINED THIS...........THE RAIN TO STOP AND THEN THEN THE HARVEST.


3) The flowers appear on the earth; THIS HAS TO BE IN THE SPRING....WHEN THEY APPEAR..........IT IS NOT IN FALL , WINTER OR EVEN THE SUMMER HEAT. FLOWERS APPEAR EVEN IN THE GRASS IN THE SPRING B4 IT GETS HOT.


4) The time of singing has come, IT WAS TRADITIONAL FOR THE HARVESTERS TO SING...........WHEN THE HARVEST SEASON STARTED.



5) And the voice of the turtledove Is heard in our land. THE TURTLE DOVE APPEARS IN MARCH/APRIL IN ISRAEL. THEY SPEND THE WINTER IN THE SOUTH.....IN AFRICA, AND HEAD NORTH THRU ISRAEL TO EUROPE IN THE SPRING.............TO SPEND THE SUMMER IN EUROPE.



6) The fig tree puts forth her green figs... THE LITERAL HEBREW SAYS THE JUICE STARTS TO FLOW INTO THE FIGS TO START TO RIPEN THEM. IE SPRING.


7) And the vines with the tender grapes Give a good smell. THESE ARE THE VERY FIRST 'TENDER GRAPES', THAT WILL BE READY AFTER THE SUMMER HEAT......BUT THEY START TO BLOSSUM OUT IN THE SPRING!
 

Rise up, my love, my fair one, And come away!
