Rotating shift calendar for nurses, firefighters and plant crews

The problem

Rotating schedules such as 2-2-3 or 24-on/48-off don't fit weekly calendar apps, so shift workers re-enter shifts by hand or keep a paper chart on the fridge. Partners and kids can't tell at a glance which days are free. Popular shift apps put calendar sharing or export behind a paid tier.

For: Nurses and hospital staff · Firefighters and EMTs · Plant and warehouse crews · Families of shift workers

Why now

BLS data released on September 24, 2026 show that 15% of US wage and salary workers usually work a non-daytime schedule, and 1.9% work rotating shifts.
