The breeding time is not likely related to the atomic number of iron (there have been several posts about this). All other gemstones have breeding times based on the days in a month. I believe the jade breeding time is the average number of days in a month. Over 4 years we have 365*3+364 = 1461 days. Divide by 48 months to get 30.4375 = 30 days, 26 hours.
