Built in Go, `askgit`

is an open source CLI and *coming soon* web interface (linked above). With this tool in your toolbox, you can mine your repo for info like commit count by author on each day of the week:

```
SELECT
count(*) AS commits,
count(CASE WHEN strftime('%w',author_when)='0' THEN 1 END) AS sunday,
count(CASE WHEN strftime('%w',author_when)='1' THEN 1 END) AS monday,
count(CASE WHEN strftime('%w',author_when)='2' THEN 1 END) AS tuesday,
count(CASE WHEN strftime('%w',author_when)='3' THEN 1 END) AS wednesday,
count(CASE WHEN strftime('%w',author_when)='4' THEN 1 END) AS thursday,
count(CASE WHEN strftime('%w',author_when)='5' THEN 1 END) AS friday,
count(CASE WHEN strftime('%w',author_when)='6' THEN 1 END) AS saturday,
author_email
FROM commits GROUP BY author_email ORDER BY commits
```
