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: 204
  • Daily file updates (only one update per file and date counted): 450
  • First update: 2014-09-09
  • Latest update: 2022-03-05
  • Days between first and latest update: 2735 (390 weeks, estimated 1950 working days)
  • Active days (at least one file change): 274
  • Data:
