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: 6667
  • Daily file updates (only one update per file and date counted): 18511
  • First update: 2012-01-30
  • Latest update: 2022-01-23
  • Days between first and latest update: 3647 (521 weeks, estimated 2605 working days)
  • Active days (at least one file change): 2478
  • Data:
