title: Ethiopian calendar in Android
body: <p>I am developing an Android app for an Ethiopian company and have to deal with dates.</p>
  <p>The calendar used in Ethiopia is similar to the Gregorian one but has two main differences: it's set approx. 7 years earlier and has 13 months.
  At the time I post this question the date is 13-09-2021 in the Gregorian calendar and 03-01-2014 in the Ethiopian one.</p>
  <p>My questions are:</p>
  <ul>
  <li><p>does Android support the Ethiopian calendar and is it customary for people in Ethiopia to have their devices use it?</p>
  </li>
  <li><p>if so, do I have to get the default formatter (that uses the default calendar: <code>Calendar.getInstance()</code>) in order to format the date properly?</p>
  </li>
  <li><p>instead, if the device uses the Gregorian calendar how does Java support the translation to the Ethiopian date?</p>
  </li>
  </ul>
  <p>What would you suggest in order to simulate the full scenario, with the device set with the proper current Ethiopian date (as if coming from the network provider) and locale?</p>
