It can be flown whenever you want it to be. But to answer the question SHOULD it be flown in the rain, no. It should be flown when the weather permits from sunrise to sunset, unless it's an all weather flag. The American should be displayed 365 days a year from sunrise to sunset, with the exception of days it is raining. If it is raining at sunrise, you do not raise the flag. If it is not raining at sunrise, raise the flag; and if it starts to rain during the day, no matter the flag still stays up and you take it down at normal sunset.
No
None on US soil.
NO. as approved by congress "NO STATE FLAG" shall be flown above the American Flag.
Flags flown from tall masts can be flown 24 hours if illuminated at night. Flags flying from short poles have to be lowered at sunset.
THE US FLAG CAN BE FLOWN DURING THE DAY, ANYTIME. THE FLAG CAN ONLY BE FLOWN AT NIGHT IF IT IS PROPERLY LIGHTED.
Any state flag should be flown below or level with the US Flag, but never above it. If it is on the same level it should be on the right, this includes Texas. The rumor that Texas is the only state that is allowed to fly at level with the US Flag is just that a rumor and an urban myth.
texes
All Day. It can be flown at night if a light is shined on it.
The American Flag should always be flown higher than the state flag and should be flown a half-mast when in peril or in rememberance.
The U.S. flag should be flown from dawn to dusk. If flown at night, it is to be illuminated.
