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: 278
  • Daily file updates (only one update per file and date counted): 365
  • First update: 2005-04-21
  • Latest update: 2022-01-17
  • Days between first and latest update: 6116 (873 weeks, estimated 4365 working days)
  • Active days (at least one file change): 2582
