I know; I should like dawn as it promises many possibilities! But I always liked dusk better which should mean that one has taken advantage of the day.
It all goes back to one of my favorite literary elements from William Shakpeare’s Macbeth:
Be innocent of the knowledge, dearest chuck,
Till thou applaud the deed.
Come, seeling night,
Scarf up the tender eye of pitiful day;
And with thy bloody and invisible hand
Cancel and tear to pieces that great bond
Which keeps me pale!
Light thickens; and the crow
Makes wing to the rooky wood:
Good things of day begin to droop and drowse;
While night’s black agents to their preys do rouse.
Thou marvell’st at my words: but hold thee still;
Things bad begun make strong themselves by ill.
So, prithee, go with me.
