Time and calendars

The 8th Thing is Calendars - electronic calendars and their uses.

'Explore your phone's calendar app and its alert function'. Yes I do that have even been known to set the second alert for some appointments. 

The calendar on the library's website utilises Google Calendars and has the ability to copy its events to your calendar. 
My emails are via Outlook and Yahoo's Mail app, both with calendar functions.
We use Envisionware's PCRes to book library public computers, great that it also counts down their session time and alerts them when approaching the end of the session (has stopped lots of arguments). In some branches it is coupled with LPTOne print management which  governs printing from the pcs (which has stopped even more arguments resulting from 'accidentally' generated copies). 
Have had experience with ticketing sites like Eventbrite for event registrations that prompt your calendar. 

Then there's a whole array of online calendars you encounter when registering events booking, training, conferences, etc.

The electronic reminder/alert is a great assistance to ring a bell/send a message when something may have slipped by the human calendar.

Yet I think there's still a role for the humble print calendar in conjunction with the electronic - even if it is just for it's art.
