annual cycle
One year's rotation
An annual cycle is a sequence of events or changes that repeats every year.
The term applies to natural phenomena—the annual cycle of seasons, the salmon's annual cycle of migration and spawning—and to human activities like budgeting, academic calendars, or religious observances.
In ecology and biology, annual cycles govern breeding, dormancy, and migration patterns.
