To loose 2 kg in a month how much calorie should you burn everyday?

2 kg= 14,000 calories of fat so you will need to burn 500 more calories than you consume every day for a month (assuming that you don't eat any more than you do now). Initial weight loss can be far greater than this as the body will burn glycogen stores first. 2 kg of glycogen is about 7,000 calories plus the 6 kgs of water that it holds onto. So 1,000 calories used up can lead to a 1kg weight loss but this is not permanent. Vigourous exercise can also raise metabolism for some time after exercise so this will reduce the number of calories you have to burn through exercise. Also an damage you do to your body (as hard exercise will slightly damage muscles that is why you are sore after exercise) will have to be repaired this will also burns calories. Lastly any exercise you do will lead to increased muscle this also costs calories. It is best to concentrate less on weight loss than reducing flabby bits.
