Onboarding DOB timezone shift auditCustomer & Account Analytics

Task prompt

CX is seeing card-activation date-of-birth failures again, and they think it is related to a known timezone bug from onboarding. There is an engineering ticket ENG-233 ('Invalid date - DOB') that describes the defect — start there to understand what went wrong. I need you to figure out who was actually affected by this bug. Give me the blast radius: how many applications and distinct users were impacted, which way their DOB shifted, and how many of them ended up with an account. When you have the numbers, open a Slack channel called "onboarding-dob-shift-audit", post a summary of the findings and pin it. File a Jira ticket in the Bank Operations project titled "Onboarding DOB timezone shift audit" with the affected population details. Reply to me with the headline numbers.
