Confirmations are simply blocks that have been generated after the block that contains your transaction.
Because there is no central authority that can be consulted to be sure a transaction will be committed, recipients use the number of confirmations as a way of protecting against double-spend attacks.

confirmation can be seen as the approvation of a new law, when a new law it is approved it passes through many policy areas, before it is actually approved

this is the same you need 6 blocks to make sure that the transaction is legit, so 1 hours as average

On an average you will get confirmations within hour. At times it may vary based on the fee provided and the blocksize.

After a transaction is broadcast to the Bitcoin network, it may be included in a block that is published to the network.
When that happens it is said that the transaction has been mined at a depth of 1 block.
With each subsequent block that is found, the number of blocks deep is increased by one.
To be secure against double spending, a transaction should not be considered as confirmed until it is a certain number of blocks deep.
