FAR 121.434 violation Consolidation of knowledge. I got my type rating on X Date and because of the coronavirus I was sent home one day later.  Approximately 3 months had past and I went to finish my simulator training.  For that reason I thought my time for consolidation would begin 3 months from original date; which was the day I officially finished my simulator training.  Not knowing that my 120 days of consolidation [had] expired.  I accepted flights on the XXth and XYth after expiration.  Two of the flights were ferry flights the last one on the XYth was a Part 121 flight.  Therefore I unknowingly violated FAR 121.434.When I figured out what I had done I notified my Chief pilot. I misinterpreted part 121.434  by thinking that the 120 day clock for 100 hours of consolidation started on [date].  I also know that we have scheduling software that tracks flight time and duty periods for Part 117.  I thought it would track consolidation also.  I think I could have been scheduled to do a P/C check while I was completing my simulation in [month] and having a better understanding of FAR 121.434 are two things that could have prevented this issue.
