File Age

File age measurements show the distribution of file ages (days since the first commit) and the recency of file updates (days since the latest commit).

Summary
  • Number of files: 493
  • Daily file updates (only one update per file and date counted): 1893
  • First update: 2012-03-05
  • Latest update: 2022-01-17
  • Days between first and latest update: 3606 (515 weeks, estimated 2575 working days)
  • Active days (at least one file change): 3016
