If the flag is already up what time do you lower it to half mast?

If the flag is already up and it needs to be lowered to half-mast, you should first raise the flag to the top of the flagpole briefly before lowering it to the half-mast position. This practice signifies respect and honors the occasion. The specific time for lowering it to half-mast can depend on the guidelines provided for the event or observance, but typically it should be done at sunrise or at a designated time set by authorities.
