Spring turkey calendar
Michigan is Eastern-subspecies country across both peninsulas, but the Upper Peninsula breeds about two weeks later than the southern Lower Peninsula due to latitude. The state's hunt-period structure gives hunters real choice in which breeding phase to target.
Breeding phases by zone
Phases are calendar approximations driven by photoperiod — year-to-year variation is small. Peak Breeding is the toughest phase for call-response hunting; Gobbling and Post-breed are the best.

What drives turkey timing here
Eastern subspecies country at higher latitudes — peak breeding lands late April to early May. Most state seasons in this band open in late April or early May, hitting the back half of peak breeding and the post-breed gobbling resurgence.
Photoperiod (day length) is the primary trigger — same week of April year over year produces the same calling response, give or take a few days. Weather pushes the window early or late at the margins.
