Where to Find Your Active Duty Service Computation Date?

To find your Active Duty Service Computation, active duty members should pull their most recent Leave and Earnings Statement through myPay and look at Field 4, “PAY DATE,” which shows the Pay Entry Base Date in YYMMDD format. Separated and retired members should look at Block 12 of the DD Form 214, which breaks out net active service, prior active service, prior inactive service, and total combined service. If you don’t have your DD-214, you can request it from the National Personnel Records Center.

If You’re Currently Serving

Your LES is the quickest place to check. Field 4, labeled “PAY DATE,” carries your Pay Entry Base Date (PEBD), which is the date the military uses to calculate your years of service for pay purposes. Your leave balances on the same statement are driven by your service computation date for leave accrual, so the LES effectively shows you both figures at once.¹

DFAS myPay is the portal that gets you there. It serves Army, Navy, Marines, Air Force, and Space Force members and lets you view your LES, check your PEBD, and download pay statements from prior years.² If the number on your LES looks off, myPay is where you’ll notice first.

milConnect, run by the Defense Manpower Data Center, gives you a second view: DEERS information, personnel records, and benefit summaries. As of early 2026, milConnect is still operational but is directing users toward a newer DMDC Customer Connect Portal at mybenefits.mil for self-service tasks like DEERS data corrections. Navy and Marine Corps personnel can also use BUPERS Online (BOL) for branch-specific personnel records.

When You Need an Official Number But Don’t Have a DD-214

Active duty members preparing for a benefit or transition can ask their personnel office for a Statement of Service. It’s an official letter confirming your periods of active duty and typically reflects two key dates: the Pay Entry Base Date and the Active Duty Service Date (ADSD), which accounts for all periods of active federal military service across all statuses, including commissioned, warrant, and enlisted time.³

If You’ve Separated or Retired

The DD Form 214, Certificate of Release or Discharge from Active Duty, is the single most important document for verifying your service computation as a veteran. It’s issued when you separate from active duty or complete at least 90 consecutive days of active duty training.⁴

Look at Block 12. Its subfields cover the net active service for the period this particular DD-214 covers, any prior active duty service, any prior inactive service, and total combined service. The form also records your date of entry into active duty and date of separation, so you can check the math yourself.⁴

If you served across multiple enlistments, you’ll have more than one DD-214, and you need all of them to reconstruct your full ADSC. A single form only shows the service tied to that separation plus what the personnel system knew about prior periods at the time.

Requesting Your Records If You Don’t Have Them

The National Personnel Records Center (NPRC), part of the National Archives, holds military personnel records after separation. You have three ways to request your DD-214 and related documents: online through the eVetRecs system, by mailing Standard Form 180, or by faxing that same form. Veterans and next-of-kin of deceased veterans can use eVetRecs directly; others should use the SF-180.⁵

Build in time. NPRC response times regularly run 90 days or more, and requests involving older records or extensive research can take six months or longer.⁶

The VA has absorbed most of what the old eBenefits portal did. To request your DD-214 digitally on the VA side, start at VA.gov rather than eBenefits.⁷

If NPRC Says Your Records Are Missing

A 1973 fire at the records center destroyed an estimated 16 to 18 million official military personnel files, with no backup copies, microfilm, or indexes in existence at the time. Army records for personnel discharged between November 1, 1912, and January 1, 1964, lost roughly 80 percent of their files. Air Force records for personnel discharged between September 25, 1947, and January 1, 1964, suffered about 75 percent losses.⁸

If your file was in the fire, NPRC will attempt to reconstruct your service history from alternative sources like unit rosters, pay records, and VA claim files. Any documents you kept yourself, whether enlistment paperwork, separation papers, or old LES printouts, will speed that process considerably.

What the Number Actually Represents

Your ADSC is the total creditable time you’ve spent in uniform. Congress defines what counts: all periods of active service as a commissioned officer, warrant officer, or enlisted member of any uniformed service, plus active duty for training and certain reserve component duty.⁹

Not every day in uniform automatically counts. Time lost to unauthorized absence, desertion, confinement connected to a trial, or inability to perform duties because of misconduct doesn’t add to creditable service. Enlisted members must make up the lost time before their obligation is complete. Officers don’t make it up, but the lost period can’t be counted toward length of service for purposes other than basic pay.¹⁰

One exception: if a confinement-related charge is dismissed or results in an acquittal, the Secretary of the relevant branch must waive the lost-time penalty.¹⁰

Knowing what counts helps you sanity-check what you find. If your LES or DD-214 shows a number that doesn’t match your own count of qualifying periods, one of the two is wrong.

What to Do If the Number Is Wrong

While You’re Still Serving

Take it to your unit’s S-1 or personnel office. Many mistakes, like an incorrect PEBD or a missing period of prior service, are fixed at the administrative level without a formal board application. Bring documentation: old LES printouts, enlistment contracts, prior DD-214s, and orders showing active duty periods. The earlier you raise it, the simpler the correction.

After Separation

Veterans and former service members with records errors that can’t be resolved through normal channels can apply to the Board for Correction of Military Records for their branch. Each military department has its own board, authorized by federal law to correct any military record when necessary to fix an error or remove an injustice.¹¹

The application is DD Form 149, Application for Correction of Military Record, submitted with supporting evidence. Strong applications include copies of relevant military records you have in your possession, statements from people who served with you who can confirm the error, and any other documentation that supports your case.¹²

Army personnel have an extra step: you must exhaust all lower-level administrative remedies before the Army Board for Correction of Military Records (ABCMR) will consider your application.¹³

The filing deadline is three years from when you discover the error or injustice, though the board can waive it if doing so serves the interest of justice.¹² Boards do grant late applications, but the further out you are, the harder it is to gather evidence. Once you’ve found a discrepancy, act on it.
