Heisei 31 is this year. Heisei 32 and above are the ones that don't exist.

  Thankfully I don't live in Japan and have to deal with that system on a daily basis.

    It's been thirty years since anyone has to touch that code.

      Some systems are even still on the previous era (shōwa). Some may even hit a Y2K-like problem in 2025 (shōwa 100).

        I'm now imagining some kind of action movie where the emperor lives too long and a band of programmers have to assassinate them lest their code breaks.

  Isn’t Reiwa 1 also this year?
  • fenomas 8y ago
    It's both - dates through April 30 are Heisei 31, and dates from May 1 are Reiwa 1, is the official take.

      Well, I don't foresee that causing any bugs.
      • thaumasiotes 8y ago
        Bugs of that type should have been worked out long ago; it is not the norm for the era change to coincide with the new year.
        • Nullabillity 8y ago
          It is not the norm to reset your date system every 30 or so years.
          • thaumasiotes 8y ago
            ...yes it is?
  • glandium 8y ago
    From May 1st onwards, yes. Heisei 31 April 29, Heisei 31 April 30, Reiwa 1 May 1, Reiwa 1 May 2, etc.
