When Is Earth Overshoot Day 2024 Calendar. This is the date when humanity’s demand on natural resources exceeds earth’s. To determine the date of earth overshoot day for each year, global footprint network calculates the number of days of that year that earth’s biocapacity suffices to provide for humanity’s ecological footprint.
