Emergency Calendar (eCal) lets you create and display any shift calendar used by fire departments and emergency medical services (EMS). eCal was designed for low-tech, easy use to allow users to personally customize their shift schedule -- whether it's a 2/4, 4/6, 48/96, or any other Platoon/Kelly combination.

*** IMPORTANT (Please Read) ***

The Emergency Calendar creates' any Kelly/Platoon schedule by using the repeating pattern unique to that specific schedule. For that reason, it is important that the User only includes one complete Rotation/Cycle when creating their calendar.

2/4 Kelly = 12-day Rotation/Cycle/Tour
3/4 Kelly = 9-day Rotation/Cycle/Tour
4/6 Kelly = 24-day Rotation/Cycle/Tour
48/96 Platoon = 6-day Rotation/Cycle/Tour

Please DO NOT attempt to schedule by week, month or single "go-around", as these do not reflect the pattern that determines each schedule.

Easiest to visit the website:


To get to the EDIT CALENDARS view, press the third button at the bottom of the screen. The pre-existing calendars will show up in a list.


You can delete calendars, change their position by dragging them, or select them to edit. You can add a new calendar to the list by clicking the ADD CALENDAR button to the bottom right.


To create a custom calendar, first enter the calendar NAME in the top text field. To customize the schedule, select the START button and then click the start date of the first day of a given cycle. (For example, 2/4 Kelly = 12 total days; 4/6 Kelly = 24 total days; 48/96 Platoon = 6 total days.) Then select the END button and click on the last date of a single, completed cycle. Once you have selected the Start and End Dates, the Start date will be highlighted in green, the End date will be highlighted in red, and the dates in between will be highlighted in yellow. To configure the appropriate colors for their respective shifts, select a color at the button of the screen and then click on the corresponding dates in the pattern. Once the colors are filled in, SAVE the calendar. When you return to the original calendar list, you will see it has been added to the list of other calendars. To view the new calendar, click the VIEW CALENDARS button at the bottom left of the window. The schedule you made will be repeated throughout the calendar.

Constantly crashing break ,

Still not working

Unless I just need some instructions on how to use this app, which I can't find...just trying to create my own shift calendar and it can't even keep a day a certain color without messing up when you move on to the next 48hours, really frustrating.

This does not work

After receiving a message from the developers, there was an unknown problem with this app and the iPad. They have since corrected the problem and now the app works as advertised. I give these support people 5 stars now, and for now I will give the app 5 stars as well. Thanks for fixing the problem guys!

Not sure why so many people have issues with this app. Great customer support and it's the only shift calendar for multiple departments. The best. Hands down.
