Is there a way to keep the SharePoint calendar entries in order?

[georgesOne]

Hi All:

We have a movement calendar in SharePoint where people make entries where they are on which day... such as

AX - Tokyo
BY - New York

Is there a way to ensure that AX is always on top of the calendar entries, if this person makes an entry? Currently, it looks as if the first person who makes an entry for that day stays on top.

Thanks for any help, georgesOne
