It depends where from
Nobody really knows because the black bird wasn't ment to travel.
In 1990 the SR-71 went from the West Coast to the East Coast in 68 minutes and 17 seconds. That's as close as I could get to Los Angeles to New York.
The SR-71 Blackbird, a long-range, advanced reconnaissance aircraft, famously made the flight from New York to London in just under 2 hours. This remarkable speed was achieved thanks to its ability to cruise at over Mach 3. The record-setting flight occurred on July 22, 1974, demonstrating the aircraft's unmatched speed and performance capabilities.

The time it would take a blackbird to fly around the Earth depends on its speed and the distance to cover. A blackbird can fly at speeds of about 20 to 30 miles per hour. The Earth's circumference at the equator is approximately 24,901 miles. At an average speed of 25 miles per hour, it would take the blackbird around 1,000 hours, or about 41.7 days, to complete the journey without resting.
Depending if you travel from pole to pole or aroung the equator, it takes just under 11 hours from pole to pole. The earth is not a perfect sphere so pole to pole is a little bit shorter distance versus going around the equator.That is at MACH 3.4 (2,200 MPH) and if it could do the trip without having to stop for fuel.
It took 68 min 17 sec.
