# Epoch Concept

The epoch will serve as the central unit of time in the new tokenomics. An epoch consists of a number of 30 days. It will be used to determine the [ParaBoost](/governance/parallel-governance-token-prl/tokenomics/paraboost) calculation period, the duration of the cooldown during unstaking sPRL1 and sPRL2 and to manage the [fee sharing](/governance/parallel-governance-token-prl/tokenomics/fee-distribution) distribution to sPRL1 and sPRL2 holders.
