Hi, I am a scout leader and we are raising the flag tomorrow at our local high school football game. From what I have read, the flag should be at half staff until sunset. Can anyone tell me what "sunset" is considered?! The local weather page says that sunset is at 7:46 that day. We will be raising the flag at approx. 7:15. Any suggestions? I am available at the game to raise the flag at 7:46 if necessary! Please help! Thanks!
