Thank you for your interest in Shift Calendar, the app designed by Firefighters and built for Firefighters. Shift Calendar is the full functioning, eternal shift calendar specifically for the professional firefighter, paramedic, EMS worker, their family and friends. No more checking shift cards to see if you will be working or off on your anniversary, birthday or other important events. This version of the Shift Calendar is configurable to present shift schedules specifically for the following: 24/24 for departments working 2 platoons 24 on 24 off. 24/48 for departments working 3 platoons 24 on 48 off. 24/72 for departments working 4 platoons 24 on 72 off. For departments working more complex schedules such as 24 on and 24 off for 5 days with 96 off as A-C-A-B-A-B-C-B-C-REPEAT, look for our ShiftCal Kelley schedule app. Newly released is the popular 48x96 for departments working 3 platoons 48 on 96 off as A-A-B-B-C-C-REPEAT. Search on Cal30 to see these other options. Shift Calendar provides for both Alpha and Numeric shift naming conventions. As of version 2.0, users can now keep notes on each shift day. Future enhancements will target Kelly Day/ADO. Spread the word and pass it around. Most of all...Thank you for all you do...
