Block Height

The number of blocks connected on the blockchain, which includes any block proceeding the genesis block (first block) on the chain. A genesis block will always have a height of zero because nothing precedes it. The block height is a metric used to create a bearing on time in the programming world. It also serves a few other functions, such as maintaining counterparty and betting in the crypto world. Considering that a new Bitcoin block is made every 10 minutes, you can work out certain time-related pieces of information if you have the total length of the chain.
