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: 293
  • Daily file updates (only one update per file and date counted): 446
  • First update: 2018-10-26
  • Latest update: 2021-12-15
  • Days between first and latest update: 1147 (163 weeks, estimated 815 working days)
  • Active days (at least one file change): 146
