Concept

A core banking day is not simply a calendar day. Operations, branch open/close, transaction review, and batch processing need a business-date closeout.

Business date rollover decides which business date is active. EOD closes the day. Balancing makes records agree.

Why Business Date Matters

Business date affects transaction attribution, EOD batch scope, interest accrual, interest posting, rollover, reversal eligibility, reports, reconciliation, institution sign-off, and closeout.

Common Misunderstandings

Misunderstanding	Better Reading
Getting off work is EOD.	User sign-off, institution closeout, and system EOD are different.
Calendar date always equals business date.	Night processing and rollover windows may differ.
Reconciliation changes customer accounting.	It usually updates review status, not postings.
Sign-off only means logging out.	It is tied to transaction records, balancing, and closeout.
