Football games finish in 1.5 hour whereas all formats of Cricket take more time.

T20s take 3-4 hours to finish.

One day or 50 over cricket games take more than 7 hours to finish if all overs are bowled.

Test matches can run for a maximum of 5 days.

I think because cricket matches need so much time to complete and also international teams visit other countries and if they play only on weekends, one tour will run for many months.
