At 11:17 when Carrie and Charlotte are walking down the street after returning from the Bridal Show, you can see that a couple and a guy are passing by twice when the camera makes a close up while Charlotte is inviting Carrie to see her new hallway.
When Carrie returns home after spending Thanksgiving at Miranda's, the sun is shining through the windows in her front parlor. Presumably, this is the late afternoon, and her home, located at 3 Gramercy Park West, faces east-southeast. In November, sunlight wouldn't be shining directly through the front windows at that time of day.
