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: 221
  • Daily file updates (only one update per file and date counted): 292
  • First update: 2016-11-07
  • Latest update: 2022-01-17
  • Days between first and latest update: 1898 (271 weeks, estimated 1355 working days)
  • Active days (at least one file change): 1034
