"Data limitations" should be "date limitations" of course.

You can use the EPiServer Community query system to achieve this. This code snippet retrieves all blog entries created between January 6th, 2010 and April 1st, 2010:

            EntryQuery entryQuery = new EntryQuery();
            CriteriaGroup criteriaGroup = new CriteriaGroup();

            entryQuery.Created = new DateTimeCriterion();
            entryQuery.Created.Value = new DateTime(2010, 01, 06);
            entryQuery.Created.Operator = ComparisonOperator.GreaterThan;
            criteriaGroup.AddCriterion(entryQuery.Created);

            entryQuery.Created = new DateTimeCriterion();
            entryQuery.Created.Value = new DateTime(2010, 04, 01);
            entryQuery.Created.Operator = ComparisonOperator.LessThan;
            
            criteriaGroup.AddCriterion(LogicalOperator.And, entryQuery.Created);
            entryQuery.CriteriaGroups.Add(criteriaGroup);

            entryQuery.OrderBy.Add(new CriterionSortOrder(entryQuery.Created, SortingDirection.Descending));

            EntryCollection entries = QueryHandler.GetQueryResult(entryQuery);

Thanks for the tip, but I got it working using BlogHandler in the end so that I get caching and everything. It was possible to pass null for the IUser reference. The Blog.GetEntries call failed because it would filter down to a BlogHandler call where the flag "byPublishDate" would be false which probably messed things up since I'm interested in the creation date.
