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: 64
  • Daily file updates (only one update per file and date counted): 168
  • First update: 2019-09-05
  • Latest update: 2021-12-28
  • Days between first and latest update: 846 (120 weeks, estimated 600 working days)
  • Active days (at least one file change): 63
