How this tool works
This calculator counts your age in completed years, months and days on January 31, 2026, the CBI cut-off date for Scale IV Officers, and compares it with the age limit (20–45 years) after adding your category's relaxation. Exactly the minimum age on that date counts as eligible; reaching the maximum age on that date does not, and the result shows the birth-date range to compare with the notification.

Frequently Asked Questions
Is this age calculator officially provided by CBI?
No. FreeApplyTools is an independent utility platform. However, our engine is hardcoded to strictly follow the official CBI notification rules and cut-off dates for 2026. We recommend using this as a quick reference, but always cross-check with the official CBI notification for your specific exam and post.
What is the official Cut-off Date for age calculation?
For the 2026 cycle, CBI calculates your exact age as on January 31, 2026. Our calculator automatically uses this exact date.
Common Scale IV Officers Age Eligibility Errors
"Applying under wrong category relaxation"
Many candidates select General instead of their eligible reservation category, missing out on age relaxation of up to 5–10 years for OBC/SC/ST.
"Incorrect DOB entered during registration"
Even a single-day typo can render you ineligible. Always cross-check your DOB against your 10th certificate before submitting.
"Cut-off date confusion"
CBI calculates age as on January 31, 2026 — not the exam date or application date. Our calculator already uses this exact date.
