What's happening is that each day-of-the-week column is, at a minimum, as wide as it needs to be for the widest entry in that column.
The problem is that calendar entries will wrap only on whitespace, so if you have an event with a long string in it, the column it's in will be wider. E.g., an event with the text This is an event with spaces will wrap nicely, but one with ThisEventDoesNotHaveAnySpacesInIt will be rather wide, since it can't split the text to wrap.
If you shorten the long strings or intersperse with spaces, then that column will be the same width as the other days.
When you double-click an existing event to edit or delete it, if it's a repeating event you'll normally effect the entire series of events - i.e., edit or delete them all*. To modify only a single instance of the series, click the date displayed on the calendar for the instance you're interested in (click the day number.) That will display a form listing all events on that day, with "Edit" and "Delete" buttons. For repeating events, you'll also see options for "All" or "Only this Date". Make sure "Only this Date" is selected, then press the "Edit" or "Delete" button to edit or delete that one instance.
* There's actually a preference setting in the "Event Edit Form" settings page that affects this - "Default for Repeating Events" - you can choose between "Entire Series" and "Only this Instance".
The problem is likely that the link or bookmarked URL you're using has an old date specified in it. If you remove that from the link, the calendar will go to the current date.
For example, use something like this:
If the calendar has no owner email set, then password reminder emails cannot be sent. To set the owner's email address, go to "Settings" for your calendar, then click "General Settings".
This is the forgotton/lost password feature. If somebody tries to login to a calendar but gets the password wrong, they can click a button to have the passwords emailed to the owner of the calendar.
The email goes only to the email address registered as the owner. The email will show the IP address of the person who made the request, in case that's of interest to you.
Unfortunately Facebook won't allow the calendar to display directly on your Facebook page, but you can have a link to the calendar there. Then people can click that to bring up the calendar; use a URL something like this:
You can't do this directly, but if you send us a request we can remove it. Please use our contact page to do that, and be sure to include the password for Administration for the calendar, so we can confirm that it's yours.
Also, calendars that have had no changes made for 6 months are automatically removed. You can set passwords so nobody can see your calendar in the meantime; and you can also delete all event data from your calendar. See the "Delete Events" option from the Settings page for an easy way to do that.
