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: 3951
- Daily file updates (only one update per file and date counted): 27752
- First update: 2015-02-06
- Latest update: 2022-02-02
- Days between first and latest update: 2554 (364 weeks, estimated 1820 working days)
- Active days (at least one file change): 2134
