Your contract's yearly list — usually 8 tours (4 day + 4 night). Add each one; they'll show on the calendar in blue.
Status & Time Off
Punch in vacation, medical leave, or light duty. Vacation & medical leave = you’re off. Light duty lets you set the schedule you actually work — your group chart, an ABCD letter, or a custom weekly schedule. Vacation needs an end date. Medical & light duty can stay open; set an end date to go back to your regular tours.
Light-duty schedule — the schedule you actually work while on light duty
Light-duty gig name — where you’re working (optional)
Your letter
Days you work
This is your usual week. Change or turn off any single day later by tapping it on the calendar. Overtime on an off day (like a Saturday) → open that day and add it as Other OT.

🚚 6-month detail — you’re temporarily assigned to another firehouse. Your own calendar follows your detail group for the window and switches back on your return date; your home house shows you “on detail” and drops your tours until you’re back.Your group at the detail house (1–25)Set the End date above to your return date.
CFR Refresher
CFR (certified first responder) has to be renewed — usually about 4 years from your last refresher class. Enter your expiration date and you’ll get a reminder as it gets close.
CFR expiration date
Enter the date your CFR expires (on your card / from BHS). It’s usually about 4 years from your last refresher’s test-out day.
Schedule your CFR refresher
Pick the 5 class days — the 5th is the test-out day (your new expiration). You stay full duty; each class shows on the tour & time you pick. Edit anytime.
Education & Medicals
Mark a one-day event — it shows on the 9× day tour of that date. Pick the type and the date.
Company Events
Name it, add one or more dates — pick each day, or auto-fill a weekly/monthly run, then remove or add any day. Every date gets highlighted in your color.

Everything you're owed, added up. Tap a year → month → pay period to drill in, then tap any day to jump to it on the calendar.
Backup & Restore
Your calendar lives on this device. Back it up so a new phone, a cleared browser, or a lost device won't wipe it.
1 · Save a backup
Copying the code is the surest way — paste it into Notes, email it to yourself, or drop it in a password manager.
2 · Restore onto a device
Open this calendar on the other device, then paste your code or pick your file. This replaces whatever is on that device.
3 · Cloud backup OFF
Auto-saves an encrypted copy to the cloud after every change — only your recovery code can unlock it. On a new or wiped phone, enter the code to get everything back.

Mutuals Ledger
Every partner mutual you record, tallied by name. Mutual in = you covered their tour, they owe you one back. Mutual out = they covered you, you owe them. Add a name to each mutual in the day view and it lands here.

Reassigned to new groups (and maybe a new partner)? Add the date it takes effect. Your old tours and everything you logged stay exactly as they were — only dates on/after the change use the new groups.

ABCD Chart
On the ABCD chart you're assigned a letter and work that letter's days — both the 9× and the 6×. Turn it on for the dates it's in effect and pick your letter. Leave the end date open and set it later when you switch back. Your square-root tours before & after are untouched — and you can still pick up overtime and mutuals on the other letters' days, and add your marks & notes to each tour.
