A team of physicists with NASA's Jet Propulsion Laboratory at the California Institute of Technology has calculated more precisely how much faster time passes on the moon than on the Earth. The paper describing the math they used to make the calculations and their results has been posted to the arXiv preprint server.

    the team found that time on the moon ticks by at 0.0000575 seconds faster per day (57.50 µs/d) than it does on Earth. Based on that number, other calculations can be made—if a person were to live on the moon for 274 years, for example, they would be 5.76 seconds older than they would be had they lived on Earth all that time.

      I wonder why the article doesn’t show time elapsed per year instead.

      If a person were to live on the moon for one year, for example, they would be 0.02 seconds older than they would be had they lived on Earth all that time.

        Yeah, 274 years is such a weird time length to use. 0.02 seconds per year is better, or if you wanted to do a “lifetime” measurement it’s about 1.68s over 80 years.

    Okay, TIL: it passes faster due to a shallower gravity well, rather than my expectation that it would pass slower due to its orbital velocity around the earth.

    For astronauts in LEO, time passes slower because of the latter.
