How to find the Index Creation /Rebuild Date in SQL Server

This query which uses STATS_DATE() function to get the STATISTICS updated date. This will not give you accurate result if you are updating STATISTICS explicitly. The logic behind the query is, if you rebuild indexes the STATISTICS are also being updated at the same time. So if you are not explicitly updating STATISTICS using UPDATE STATISTICS tableName command , then this query will give you the correct information
--In SQL Server 2000
Select Name as IndexName, STATS_DATE ( id , indid ) as IndexCreatedDate
From sysindexes
where id=object_id('HumanResources.Employee')
-- In SQL Server 2005
Select Name as IndexName, STATS_DATE ( object_id , index_id ) as IndexCreatedDate
From sys.indexes
where object_id=object_id('HumanResources.Employee')
