 jubilee
      n : a special anniversary (or the celebration of it)

 Jubilee
    a joyful shout or clangour of trumpets, the name of the great
    semi-centennial festival of the Hebrews. It lasted for a year.
    During this year the land was to be fallow, and the Israelites
    were only permitted to gather the spontaneous produce of the
    fields (Lev. 25:11, 12). All landed property during that year
    reverted to its original owner (13-34; 27:16-24), and all who
    were slaves were set free (25:39-54), and all debts were
    remitted.
      The return of the jubilee year was proclaimed by a blast of
    trumpets which sounded throughout the land. There is no record
    in Scripture of the actual observance of this festival, but
    there are numerous allusions (Isa. 5:7, 8, 9, 10; 61:1, 2; Ezek.
    7:12, 13; Neh. 5:1-19; 2 Chr. 36:21) which place it beyond a
    doubt that it was observed.
      The advantages of this institution were manifold. "1. It would
    prevent the accumulation of land on the part of a few to the
    detriment of the community at large. 2. It would render it
    impossible for any one to be born to absolute poverty, since
    every one had his hereditary land. 3. It would preclude those
    inequalities which are produced by extremes of riches and
    poverty, and which make one man domineer over another. 4. It
    would utterly do away with slavery. 5. It would afford a fresh
    opportunity to those who were reduced by adverse circumstances
    to begin again their career of industry in the patrimony which
    they had temporarily forfeited. 6. It would periodically rectify
    the disorders which crept into the state in the course of time,
    preclude the division of the people into nobles and plebeians,
    and preserve the theocracy inviolate."
