Why put pollen in your calendar
If you have hay fever, the useful question is not "what is the pollen count right now" but "which days this week are safe for the long walk, the outdoor dinner or the run". A calendar answers that at a glance, because it is already where you decide what happens when.
What Pollen Calendar shows
Pollen Calendar adds a 5-day pollen forecast as all-day events, only for the allergens you care about. You can pick from 12: grasses, birch, alder, hazel, ash, oak, olive, pine, cottonwood, ragweed, mugwort and juniper.
Each day is color-coded green, yellow, orange or red, so a glance at the month view shows the good days. A typical event reads "🟠 Pollen: Grasses High, Birch Moderate".
Setup in 2 minutes
1. On a computer, install Pollen Calendar from the Google Workspace Marketplace.
2. In Google Calendar, open it from the right sidebar, set your location and tick your allergens.
3. Five days of pollen levels appear and refresh every morning, on every device.
Where the data comes from
Forecasts come from the Google Pollen API and cover more than 65 countries. Events are marked free and never trigger reminders.
Pollen Calendar is an informational tool, not medical advice. Talk to your doctor about treatment.
