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: 606
  • Daily file updates (only one update per file and date counted): 1118
  • First update: 2017-07-27
  • Latest update: 2022-01-12
  • Days between first and latest update: 1631 (233 weeks, estimated 1165 working days)
  • Active days (at least one file change): 500
