Flag at half mast

I don't know but I think it is silly if it is. I think it would be sillier to get upset about it.

Maybe for Presidents day on Mon??

And it's not silly to get upset about the flag being half staff for Whitney. It SHOULD'T be for her. Yes she was talented but imo it doesn't make someone qualified for the honor of the flag being half staff.

It could be something completely different, maybe someone who works for them passed?

According to the US Flag code, the flag should only be at half-staff on Memorial day (until noon). Any other half-staff occasion is supposed to be by the order of the President.

The flag, when flown at half-staff, should be first hoisted to the peak for an instant and then lowered to the half-staff position. The flag should be again raised to the peak before it is lowered for the day. On Memorial Day the flag should be displayed at half-staff until noon only, then raised to the top of the staff. By order of the President, the flag shall be flown at half-staff upon the death of principal figures of the United States Government and the Governor of a State, territory, or possession, as a mark of respect to their memory. In the event of the death of other officials or foreign dignitaries, the flag is to be displayed at half-staff according to Presidential instructions or orders, or in accordance with recognized customs or practices not inconsistent with law. In the event of the death of a present or former official of the government of any State, territory, or possession of the United States, the Governor of that State, territory, or possession may proclaim that the National flag shall be flown at half-staff. The flag shall be flown at half-staff thirty days from the death of the President or a former President; ten days from the day of death of the Vice President, the Chief Justice or a retired Chief Justice of the United States, or the Speaker of the House of Representatives; from the day of death until interment of an Associate Justice of the Supreme Court, a Secretary of an executive or military department, a former Vice President, or the Governor of a State, territory, or possession; and on the day of death and the following day for a Member of Congress.
