My flight review expired at the end of month.  I had been in State X for most of next month and then spent two weeks in place Y for yet the next month.  When I returned the COVID-19 pandemic was starting to take over everyone's life.  I had no time for flying in that period; until I was asked to fill in for an instructor who was leaving.  For whatever reason; I never looked at my Flight Review date and missed it.  I flew on that date and four subsequent dates before something made me look.  I was out!  Inattention to details has never been a problem till Coronavirus came along.  Purely human error - mine.  Sorry.
Pilot reported being outside of flight currency requirements and cited distraction from the COVID-19 pandemic as a contributing factor.
