GitHub arranges daily contributions by week and weekday, with a yearly total above the grid. The five color levels make the calendar compact but limit precise comparisons between days. In this active profile, many cells have similar shades, making variation harder to see. The weekday rows still provide a useful way to look for recurring gaps or patterns.
