There are three Daily Challenges available in the Path of Valor, and they change every day. You only have 24 hours to complete them.
Some Daily Challenges have special requirements, such as completing Special Stages or crafting special Battle Items. You receive Valor Points for each completed Daily Challenge, so make sure to complete as many of them as you can each day!
