How long will Ubuntu 13.04 be supported for? [duplicate]

The ubuntu wiki has a graph for this (see https://wiki.ubuntu.com/LTS for more information).

Ubuntu also has a 6 months cycle where new releases are release on the 4th and 10th month of the year (hence the 12.04, 12.10, 13.04, 13.10 etc).

A new LTS version is released every 2 years. In previous releases, a Long Term Support (LTS) version had 3 years support on Ubuntu (Desktop) and 5 years on Ubuntu Server. Starting with Ubuntu 12.04 LTS, both versions will receive 5 years support. There is no extra fee for the LTS version; we make our very best work available to everyone on the same free terms. Upgrades to new versions of Ubuntu are and always will be free of charge.

According to wiki Ubuntu, 13.04 will be supported until: 2014.10 (October)

That's the official support. But Ubuntu get's a new version every 6 months. So next one after 13.04, is in October 2013, called 13.10
