@Khalid i want to get rid of cell reference and text function as you see in cell E7 input is only date and for viewer it is different than date.
i.e E7 = 1/1/2015
for viewer it is Gaurav kr gautam has created this file on 1-Jan-2014
so is it possible to calculate date+6 for viewer
i.e E7 = 1/1/2015
for viewer it should be Gaurav kr gautam has created this file on 1-Jan-2014 to 7-Jan-2014
@Asheeshhope it is clear now.
