Blockchain Timestamp Converter (BTC & ETH)

Q: What is an Ethereum slot?

A **12-second period** in the beacon chain. Slots started at the Merge genesis (2020-12-01); the converter estimates slot = (t − genesis)/12 s.

Q: What is an Ethereum epoch?

**32 slots = 384 seconds (6.4 min)**. Validator duties and checkpoints are indexed by epoch.

Blockchains timestamp via block numbers and slots: Bitcoin blocks (~10 min apart), Ethereum epochs (32 slots of 12 s = 6.4 min) and slots (12 s). Converting wall-clock to block/slot estimates helps design time-locks and retry schedules.

This converter renders your date-time as Bitcoin block height, Ethereum epoch and slot number (using current network averages) for Web3 tooling and research.

When to Use Blockchain Timestamp (BTC & ETH)

Time-lock design

Estimate the Bitcoin block height or Ethereum slot by which a time-lock contract unlocks at a chosen instant.

On-chain data analysis

Map block timestamps to wall-clock when analyzing transaction patterns across BTC and ETH.

Web3 test fixtures

Generate expected block/slot numbers for SDK unit tests and simulations.

Frequently Asked Questions

What is a Bitcoin block height?

The count of blocks since the genesis block (2009-01-03). At ~10-min intervals, 2026-08-13 ≈ block height 930,000+ (estimate).

What is an Ethereum slot?

A 12-second period in the beacon chain. Slots started at the Merge genesis (2020-12-01); the converter estimates slot = (t − genesis)/12 s.

What is an Ethereum epoch?

32 slots = 384 seconds (6.4 min). Validator duties and checkpoints are indexed by epoch.

Are these estimates exact?

No — block intervals vary (Bitcoin ~10 min, ETH ~12 s nominal). The converter uses average rates, so values are approximations for planning, not oracle data.
