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: 855
  • Daily file updates (only one update per file and date counted): 1814
  • First update: 2021-08-09
  • Latest update: 2022-04-01
  • Days between first and latest update: 236 (33 weeks, estimated 165 working days)
  • Active days (at least one file change): 209
