When doing a search, I did find some threads addressing displaying the flag at half-staff at night or 24-hour basis. However, I wanted to get some opinions on my specific situation. I fly a 2.5' x 4' flag at my residence on a 5' staff attached to a bracket at a 45-degree angle with its own spotlight so will keep it up 24-hours when the weather is good. I do have a black mourning ribbon that I can attach to the top of the staff for half-staff purposes. From other threads, my understanding is if the flag is properly lit and kept displayed on a 24-hour basis, the same rules would apply to half-staff display. My question is, can I attach my black ribbon to the staff before I go to bed the night before? Say at 10:00 pm before going to bed? If attaching the ribbon from 10:00 pm to 11:30 pm the night before isn't acceptable, then there shouldn't be any issue attaching the ribbon at midnight, correct? I could stay up until midnight the day before a half-staff day but am wondering if it's necessary. Same question with un-attaching the ribbon ...as long as I unattach the ribbon by midnight on the day of observance, it should be acceptable, correct? I ask the question because I know the official code says that half-staff days should be from sunrise to sunset but I'm assuming that would be for those flags that are normally raised and lowered at sunrise and sunset and would not necessarily apply to flags that are illuminated 24-hours a day, correct? Also, the mourning ribbon I purchased is 10' long with a grommet in the middle dividing into two 5' sections. It appears slightly longer than the 2.5' x 4' flag itself as it drapes on the staff. It is really made for a 3' x 5' flag but the vendor I purchased it from said it was okay for a 2.5' x 4' flag. I'm not sure she gave me the correct information. It's not going to make anybody angry if the black ribbon drapes a few inches below the length of the flag itself, will it? Thanks!
