why sometimes it takes a lot of time to get confirmations on blockchain?

Just take it easy.There are many reasons why.Forst is blocks are full of transctions so some transactions are put on qeue.And sometimes because of transaction traffic that blockchain cant handle,think how many users online and how many transctions is processed at the same time

because now a large number of people are using bitcoin and they are transacting their money so it will take some time for confirming that number of transactions.

Sometimes its really frustating when transaction does not get any confirmation on blockchain for long long time...nowdays it is happening more regularily...for hours transaction remains unconfirmed on blockchain...what is the reason behind this?

This problem is becoming overwhelming for me. Sometimes there would be hours without a block, and sometimes there would be lots of blocks but my transaction would not be confirming.

The blocks are full sometimes, and that's why it's currently like this. It could also because you set a low fee.

I agree on the last replies ,well it depends on the transactions going to be confirmed before to be succesfull .just like in some banks need to take some minutes to be done. I think that's the only problem on blockchain.
