group range of cells according to months written in one column

[hirendra7158]

Sample workbook for Excel forum.xlsxHi, I have multiple lists like company A company B so on and on. each has multiple accounts maturing at different dates.how can I group accounts maturing in one particular month? the maturing dates are different in some accounts and same in others.
company A
account no maturity date
account no maturity date
company B
account no maturity date
account no maturity date

so company C, company D etc..

All are on different sheets, I tried to figure out with Vlook up, and filter, but could not make formula.
Any help?
