How Long Was Brittney Griner in Russian Prison?

Updated: Sep 17, 2025

Short answer: Brittney Griner spent 294 days in Russian custody—just under ten months—from February 17, 2022 (the day she was detained at Moscow’s Sheremetyevo Airport) to December 8, 2022 (the day she was released in a prisoner swap for Viktor Bout). That total covers pre-trial detention, trial and sentencing, transfer to a penal colony, and her release.

What “in Russian prison” really covered

People often use “Russian prison” as a shorthand, but Griner’s 294 days involved several stages under Russian custody: initial arrest and pre-trial detention in Moscow, court proceedings that culminated in a nine-year sentence, relocation to a women’s penal colony in Mordovia (IK-2), and finally the exchange that returned her to the United States. All of those stages are part of the same continuous period of detention.

  • Mar–Jun 2022: Pre-trial detention repeatedly extended by the court while the case moved toward trial. (Background: Reuters)
  • Jul 7, 2022: Pled guilty, saying she packed in a hurry and had no intent to break Russian law. (Report: AP)
  • Aug 4, 2022: Sentenced to nine years and fined 1 million rubles. (Report: Reuters)
  • Nov 2022: Transferred to women’s penal colony IK-2 in Mordovia. (Coverage: NYT)
  • Dec 8, 2022: Released in a one-for-one swap for Viktor Bout; returned via the UAE. (Coverage: BBC)

Total time in custody: 294 days (~9 months, 21 days). Many outlets round that to “about 10 months,” but the day-count is Feb 17 → Dec 8, 2022.

Why the “nine-year sentence” isn’t the same as time served

On paper, the sentence was nine years. In reality, sentencing in high-profile geopolitical cases doesn’t predict the time actually served—especially when diplomatic negotiations are in motion. Griner’s case followed a familiar pattern: a harsh sentence under Russian law, transfer to a penal colony, and then a diplomatic swap that ended custody months, not years, later.

Conditions she described

After coming home, Griner and her team spoke about the reality of detention: cold cells, limited hygiene products, and the shock of a penal-colony assignment far from Moscow. Those accounts track with reporting on IK-2—known for strict regimentation and hard work routines. (Background: Washington Post)

Why her detention length still gets asked

Two reasons. First, “nine years” (the sentence) keeps appearing in headlines and search suggestions, so people want the real number she served. Second, as other Americans are detained abroad, journalists and families compare case timelines—how long until charges, how fast appeals move, and when prisoner swaps become realistic. Having a precise day-count helps frame those comparisons.

What counts as “Russian prison” (a quick primer)

In Russia, defendants are typically held in pre-trial detention centers (SIZO) until trial concludes and appeals are exhausted or waived. After sentencing, they’re transported to a corrective colony (IK). Griner’s time included both phases: months in pre-trial detention near Moscow and weeks at IK-2 before the swap.

What we can verify—and how

  • The arrest date (Feb 17, 2022) and release date (Dec 8, 2022) appear consistently across major outlets. See the BBC’s release report and Reuters’ coverage of the trial and sentencing.
  • Placement at IK-2 Mordovia was confirmed by her legal team and widely reported; e.g., NYT.
  • The prisoner swap details (with Viktor Bout) and route via Abu Dhabi were confirmed by U.S. officials and reported by the BBC and Reuters.

Key takeaways

  • Exact duration: 294 days in Russian custody (≈9.7 months).
  • Legal arc: Arrest → Guilty plea → Nine-year sentence → Penal colony → Prisoner swap.
  • Why it matters: It’s a reference timeline for future cases involving Americans detained overseas and a reminder that sentencing ≠ time served when diplomacy is involved.
