Please look at the following example image and try to do the suggested tests on you calendar web page.

  • VIEW:
    • 1) we selected Week View,
    • 2) so you can display a specific week selecting a week number (in the example it is selected Week 14).
    • Try to select different views (Day View and Month View) to see the different kind of display available.
  • DAYS:
    • 3 - 4) in the example today is the 4th of April, so in both positions you can see a pale blue background. The horizontal RED LINE indicates the actual time (8.15).
    • 5 - 6) in the example the selected day is the 5th of April, in the right calendar (5) you can see a darker pale blue background, while in the “large” calendar (6) there is a yellow background. Try to select another day by clicking on it to see what happens.
  • 7) CALENDARS area, by default only the Personal Calendar is present, but you can add other calendars too. You will find more information about calendar managing in the Calendars section on this page.

The most important areas are evidenced in different ways.

Create / Modify an event

  • To CREATE an event: select New Event icon at the top left… an event window for setting a new event will open. By default events will appear in the view as a rectangular box with a dark gray background. If a pop-up window will not appear, you have to allow your browser to accept pop-ups from the SISSA calendar web site.
  • To MODIFY an event: double-click on it.

Event window

When you create or modify an event, an event window will appear to set/change its fields and options.
Fill in carefully, some options/fields are optional.

  • Title: write a name for this event (example: Meeting).
  • Location: - optional - location of this event (example: room 132).
  • Category: - optional, default value None - it could be useful only if you, changing your Preferences, customize your category list assigning a specific color to each category you wish to use. The "green" area is very small. On the right, you can see an example with the event meeting2 associated to the category Ideas marked in “green” and the Meeting event not associated to any category. About preferences management, please see the Preferences section on this page.
  • Priority: please ignore this option.
  • Calendar: if you have more calendars, choose carefully to which calendar this event belongs to. WARNING: by default the program set the selected calendar, you can change the default settings changing your Preferences.


In the “time” section of the event window, you can set the duration of the event.

  • If this event lasts the all day, you have to put a check in the box next to All day Event. The event will be displayed ONLY at the top of the calendar below the relative day/s.
  • If this event has a certain duration in time, please use the Start date and time & End date and time fields. Clicking on any of these fields, a table to help you in the selection will appear.

In this small image, there are two kind of events; 1) “Roma” is an All day Event event (two days on 12th & 13th of April) and 2) “meeting” is an event from 10:10 to 12:15 (4th of April). To enlarge this image, click on it.

  • Show Time as Free: - optional - if you put a check in this box you will appear free from commitments in case another SISSA user would invite you to participate at his event. Be aware that if the access rights of your calendar deny any kind of access to third users, for them you will appear free at any time.

Now the last three options.

  • Repeat: keep the default value “Does not repeat” if the event is unique. Otherwise, in case of repetition, you can choose the proper one (Daily, Weekly, Bi-Weekly Every Weekday, Monthly, Yearly, Custom).This is the most useful and common example of a Custom reminder.

How to set an alert as a reminder for this event.

  • Reminder: the default value of this option is No reminder. To set an alert you can choose a “Standardreminder or a Custom reminder.
    • Standardreminder: the program offers some standard reminders, from a few minutes to a week before the event. These kind of reminders show you a pop up alert ONLY if you are logged on the calendar web page. WARNING for “SHARED CALENDARS”: activating a “standard” reminder the other users could view “the pop up alert window” too, so use this option carefully.
    • Custom reminder: you may setup a custom reminder to send an e-mail alert choosing the Custom option. A new little window will appear. In our example we: 1) set 10 minutes before, 2) choose Send an E-mail, 3) put a check on Email Organizer, then confirmed these options 4) clicking on OK button. In this way, ONLY the “owner/creator” of the calendar to which this event belongs, will receive an e-mail reminder.


  • Description: - optional - detailed text description of the event.

Click on Save and Close on the top left of the window to activate the event or to confirm any changes.

Event window: Share an event

Please note: "Public Event is the default option. Be aware that to share an event with other users using a shared calendar (NOT your Personal Calendar), you have to set correctly the access rights of the shared calendar to which the event belongs. To check and eventually change the access rights please see the access rights page.

If the access rights have been already correctly set, you can choose among three privacy classification options: Public Event (this is the default option), Confidential Event, Private Event. To change the privacy classification of the selected event click on Privacy in the event window toolbar.

Event window: Attendee Invitation

  • You can send an e-mail inviting one (or more) SISSA user or an external user to participate at the selected event clicking on Invite Attendee in the Event window toolbar.
  • You can reply to a SISSA Attendee Invitation trough your SISSA calendar too.

For more information please go to Event window: Attendee Invitation page.


Delete an event

To DELETE an event: click on the event using the right button of your mouse, a drop down window will appear, then select Delete Event.
If there are a lot of  very close events, choose carefully the correct one.


Manage display events

  • To DISPLAY more information about a specific event, click once on it (see 1) in the example).
  • To DISPLAY more information about all events included in a “chosen time frame” change the View: option. The default option for View: is Today. — In the following example the view option Next 7 Days has been marked with 1a). The conference event information appears in the View section (below 1a mark), because this event is included in the “Next 7 Days” time frame (today's date is the 2nd of April).

Events appear in the main calendar as "rectangular box with a dark gray background".

In this example, you can see two other kind of events:

- 2) an event with a standard reminder (marked by a little clock in the event box). Please remember: a pop-up window will show you the reminder ONLY if you are logged on the calendar web page.

- 3) an All day Event event. In the example: a two days event titled Mission Roma with the All day Event option activated, for this reason this event is displayed at the top of the calendar.


If you find an event surrounded by a “dotted line”, this means that someone has invited you to participate at his/her event. More information on the page How to reply to an attendee invitation. Please note the "dotted line".

Display events of more calendars

The list of your calendars is on the left of the main window.
By default only the Personal Calendar is present, but you can display –at the same time– events contained in other calendars (either yours or other users calendar shared with you) PUTTING a CHECK in the square boxes next to their name.
If you remove the check from a “calendar name square box”, the events contained in that calendar will be hidden.

To add new calendars please see the Adding calendars page; to subscribe an other user's shared calendar see the Add calendars shared by other users page.

Please look at the following two examples:

  • 1) we put a check in each square box next to each calendar names, so all events from all calendars are displayed,
  • 2) the user HE has his Personal Calendar and a HE-shared-lesson calendar (shared with other users);
  • 3) the user Kim Ash shared his calendar named Kim conf. with the user HE, so HE user can see its content;
  • 4) three events (one for each calendar) are displayed;
  • 5) to understand at which calendar an event belongs to, you can click once on it, or you can change View option as shown in the window below, where we set Next 7 days view, so …
  • 6) in the view area you can see the calendar name each event belongs to.

Events will appear in the main calendar as "rectangular box with a dark gray background". To understand at which calendar an event belongs to, you can click once on it.

  • 1) now we have removed the check from Kim conf. calendar square box, so neutrons conference event is no more displayed;
  • 2) in the view area, you can see ONLY two events which belong to Personal Calendar and to HE-shared-lesson;
  • 3) & 4) in the main calendar area you can see ONLY two events as well.

Events will appear in the main calendar as "rectangular box with a dark gray background". To understand at which calendar an event belongs to, you can click once on it.

Assign to each calendar a different color. To improve the view of events belonging to different calendars, you can assign each calendar a different color.
So each event will have as background the color of the calendar at which it belongs.
Please see the Calendar properties section on this page to change the color assigned to a calendar.


This is an example with three events belonging to three different calendars.


The list of your calendars is on the left of the main window.
By default only a Personal Calendar is present, but you can:

  • add other calendars, useful to manage different activities. More information on the Adding calendars page;
  • share a calendar with other users, in order to coordinate common events. More information on the Sharing calendars page;
  • subscribe shared calendars created by other users, if you have sufficient access rights (read access at least), you can subscribe other users' calendars and a least read their content. If it is necessary, you can unsubscribe a calendar shared by other users from your calendar list. More information on the Add calendars shared by other users page.

You can display at the same time the content of one or more calendar. You can display, at the same time, one or more calendar putting a check in the square boxes next to their name. More information on Display events of more calendars section on this page.
