My favorite time to photograph is twilight. The few minutes where the light outside from the sun and inside are even makes for the best photographs (and is why I will ask to get up stupid early or out way too late). Twilight counts toward the package hours, so a day shoot can run into dusk.

Consider the following taken the same day, only a few hours apart:

Residential

Aerial view of the house and grounds in daylight
The same property at twilight, seen from a different side and a lower altitude, with the windows lit

A difference of only 90 minutes makes a world of a difference.

Commercial

Two separate buildings side by side along the street in daylight: an older brick building and a taller, narrower building faced in glass and metal panels
The same two buildings at twilight, with the interior lights on and the glass panels glowing

A difference of only 15 minutes!

Both photographs are from the VCU Technology Operations Center.
