You can observe the sun anytime - but you need to do it safely.
Easiest way to do this is to take a large cardboard box.
Cut a 1" square hole on one side of the box, and tape a piece of aluminium foil over the hole, covering it completely.
Then, take a small pin (not a nail, etc., but a small sewing pin!!) and punch ONE SMALL hole in the foil.
Take a white sheet of paper and tape it to the inside of the box, opposite the hole.
Put the box over your head, with the white paper side in front of your eyes, and the hole in the foil behind you.
Line up the hole in the foil with the sun.
The sun will appear on the paper, and the size of the box determines the size of the image - the larger the distance between the hole and the paper, the larger the image.
Enjoy!

Never look at the sun directly without proper filters. They make binoculars and even sunglasses for astronomers that allow you to view the Sun for brief periods. They also make special filters for telescopes for Solar viewing. All of these things are quite expensive however.

Whenever it is out, providing you have the right filters. Need to borrow some filters just for a peek? Try a local welding shop. Their lenses are in various shades of dark to really dark.

very early and very late in the day ( but stupid - you should always use shielding - you can't always tell when you are doing damage to your eyes )
NOTE - before actual sunrise you are seeing a refracted image of the sun - same after sunset BUT IT IS NOT SAFE - read the warning above AGAIN

Night time. Looking at the sun directly is VERY dangerous.

never, unless you want to seriously damage your eyes.

When the sun is a cold, black shiny hole. Like my heart.
