To add your availability in DigiQuatics, go to your availability (click your name then My Availability).  You'll see the current week's calendar, and you can use the arrow buttons in the upper left to navigate from week to week.  Move your mouse over the first day for which you'd like to input availability, and click the pink box that says Add Availability.  In the new window, you can choose if you want to mark yourself as available or unavailable (using the thumbs up and thumbs down button), input the times, and repeat the same availability over multiple days or weeks.  

In the example below, you can see the Guard has marked herself as unavailable for the time she has summer school classes for the month of June.   NOTE: If you input a series of availability (i.e. repeated the same availability over multiple days or week), when you edit the the availability, you will have the option to Save or Delete this day and everything in the series following this day, or you can delete the entire series.

To edit your availability, go to the My Availability page.  Use the arrows at the top to navigate to the week / day you need to edit, and select the time that you need to edit.  You can either update the times and Save, or you can Delete the availability completely.

NOTE: If you input a series of availability (i.e. repeated the same availability over multiple days or week), when you edit the the availability, you will have the option to Save or Delete JUST THIS DAY by clicking on the text for Save or Delete OR you can save or delete for this day and everything in the series following this day or the entire series by clicking on the arrow next to the button (see below).  

For time off such as for camps or vacation, you can also use the Time Off Request feature.
