year zero

Starting point, calendrically

Year zero is a reference point marking a complete break from the past—a fresh start where history begins anew.

The concept gained notoriety through the Khmer Rouge's declaration of Year Zero in 1975 Cambodia, erasing all prior culture and institutions.

The term now describes any radical attempt to reset society or ideology: The revolution promised a year zero for the nation.

In calendrical terms, there is no year zero between 1 BC and AD 1 in the common Western system, though astronomers use one for calculations.
