Mina Time Machine

Welcome to the Mina Time Machine ! This tool will help you convert time to a slot and an epoch on Mina Protocol. Or the other way around. You can also find details about ledger hash, start and end date for a given epoch. We hope it will be useful when delegating, running GraphQL queries or playing Back To the Future with you Mina's friends!

Convert Slot to Time / Time to Slot

With this converter, you can translate a time to a global slot, or to a slot in an epoch. Fill any of the field above, and the two others will update automagically!

There is know limitation to the tool: we limit the results up to 250 epochs in the future (this a moving window adjusted every epoch). Keep in mind a slot lasts 3 min. There are 7140 slots per epoch. An epoch lasts 14 days and 21 hours. We also provide API for this feature. If you need to use it, please ping us on Discord.
