Jubilees to Years (jubilee to yr)
1 jubilee equals 50 years exactly.
How to convert jubilees to years
To convert jubilees to years, multiply the number of jubilees by 50. This factor is exact. To go the other way, multiply years by 0.02.
years = jubilees × 50
Example: 10 jubilees = 500 years.
Months and years are not constant. This site uses the average Gregorian year of 365.2425 days, so one 'year' converts to 365.2425 days, not 365; use 'common year' for exactly 365 days.
About these units
Jubilee (jubilee)
Fifty years (some readings say 49), the biblical cycle after which land was returned.
Leviticus 25 tells the Israelites to count seven sabbaths of years, then to hallow the fiftieth year, when land returned to its original holders and bondservants went free. The Hebrew word yovel also meant a ram and a ram's horn trumpet, and the year was announced by a shofar blast on Yom Kippur. The English word comes from the Latin form iobeleus used in the Vulgate.
Whether the jubilee lasted 49 or 50 years is disputed. Judah the Prince identified it with the 49th year, while most classical rabbis and Maimonides read it as a separate 50th year, and some modern scholars favour 49. The figure used here is 50 years, about 1.58 billion seconds, as one common reading and a convention rather than a settled length. Practice lapsed after the exile. The Catholic Church later borrowed the name: Boniface VIII declared a jubilee in 1300, the interval was set at 50 years in 1343 and 25 years in 1470, and the 2025 jubilee ran from December 2024 to January 2026.
1 jubilee = 1,577,847,600 seconds (exactly).

Year (yr)
The average Gregorian calendar year of 365.2425 days (31,556,952 seconds). A common year has 365 days and a leap year 366.
A year is the Earth's trip around the Sun, but there are several versions. The tropical year, which tracks the seasons, is about 365.2422 days. The sidereal year, measured against the stars, is about 365.2564 days, roughly 20 minutes longer, because the Earth's axis precesses. Calendars must squeeze these into whole days, which is the origin of leap years. English year descends from Old English gear, while Latin annus, the source of annual, comes from a different root.
The Gregorian calendar, introduced by Pope Gregory XIII's bull of 24 February 1582, fixed the problem of Julian drift that had moved the March equinox away from 21 March and upset the date of Easter. Ten days were skipped, so Thursday 4 October was followed by Friday 15 October. Its rule of skipping leap days in century years not divisible by 400 gives a mean year of 365.2425 days, the value this site uses for the year. Britain and its empire switched in 1752 and Russia in 1918. Scientists write the year as a, with the Julian year fixed at 31,557,600 seconds.
1 year = 31,556,952 seconds (exactly).
