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: 299
  • Daily file updates (only one update per file and date counted): 582
  • First update: 2018-06-20
  • Latest update: 2022-03-31
  • Days between first and latest update: 1381 (197 weeks, estimated 985 working days)
  • Active days (at least one file change): 1123
