ITR-B can be filed for six assessment years preceding the relevant assessment year of the financial year in which the search or requisition was conducted. 

• If the search or requisition is completed within the same year as it was initiated:

"Y0" is the period between April 1st of the year in which the search or requisition was ordered and the last date of authorization of the search or requisition of the same year.

• If the requisition or search is conducted within a year:

"Y0" refers to the entire year of evaluation from April 1 of the year when the search or requisition began through and including March 31 of the subsequent year.

In short, "Y0" is the period from the start of the search/requisition to its completion, either within the same year or the following year.
