Round day-counts make good milestones precisely because they land at unremarkable ages. Ten thousand days falls at 27 years 4 months, twenty thousand at 54 years 9 months, and 25,000 at 68 years 5 months. They arrive without warning and mean nothing at all, which is arguably the appeal — a birthday is expected, a ten-thousandth day is not.
