How many slots did Byron era (testnet) have?
# How many slots did Byron era (testnet) have?

(Asked by: username_0 on 2022-01-30)

I was wondering the number of slots the **Byron** era (**testnet**) had or the slot number when Byron finished.

The only info I've been able to find is **systemStart": "2019-07-24T20:20:16Z"** coming from **testnet-shelley-genesis.json**.

( [Calculate timestamp from slot](https://cardano.stackexchange.com/questions/491/calculate-timestamp-from-slot) discusses about the same thing but with mainnet Byron. )

Any help would be great. Thanks in advance!
