of the company for any specific purpose like payment of dividend , bonus, right issue etc
generally book closure continues for a period of time consisting 1-2-3 days(sec 154 refer)
but record date is a particular date at the end of which list of share holders is made out
company can opt either of the methods
as per listing agreement company is required to close the books at least once a year
