Between noon and 2 the sun is directly overhead and the light is very strong, causing deep dark shadows… its harsh and makes the face look “skull” like with your neck completely dark due to the shadow from your head. Check out the photo on the left.
The photographer has to compensate for that by using extra light to fill in the dark shadows… that may be anything from using a powerful flash to additional postprocessing to using extra softbox lights to even out the dark areas. Something like the photo on the right.
Please be aware of the costing for these things and speak with your photographer beforehand about that.
The end result will be very stark and crisp, so it may not be the romantic “dreamy” look you want unless he does some Photoshop magic.
Light in the very early morning or early evening are ideal, as the suns rays are less harsh, and are “slanting” towards you. Theres also less chance of the bridal party squinting into the camera. Additionally, the red of the sunrise or sunset acts like a giant softbox, producing great rosy pink light.
Obviously you should aim for the second, but if circumstances are such that you have to go with the first try shooting in the shade near “white” areas of the building, if there are any. The sunlight bouncing off the white areas will give your photos some help in eliminating the deep shadows. Likewise for a cloudy day.
Regardless of all that I’ve just said, your photographer is a professional and should be able to work around the light, no matter what kind is available. Read the thread below for some great advice from industry professionals.
I just recalled Mrs. Swans wedding recaps and I think she was having her ceremony at about the same time… take a look at her photos to check out what to expect

And lastly, a 2PM ceremony works out pretty okay as long as you schedule your bridal party shots for an hour or so later, instead of right after the ceremony ends.
