Please what is the difference between 'Inauguration and Swearing-in.
When a new leader is inaugurated, they are formally given their new position at an official ceremony.
When a new building or institution is inaugurated, it is declared open in a formal ceremony.
If you inaugurate a new system or service, you start it.
The first of these might include an act of ‘swearing in’ (oath-taking; the act of making formal promises to fulfil the duties the new position involves) as a part of the ceremony of inauguration.
