I made a thread similar to this on finding out which service out of these is the most reliable halving countdown:
https://bitcointalksearch.org/topic/--5403419On June 21, 2022, these were the dates and the websites which they claimed for the halving:
1. BuyBitcoinWorldwide - 2 April, 2024
2. Binance Academy - 30 April, 2024
3. Gate.io - 3 May, 2024
4. CoinGecko - 4 May, 2024
5. BitcoinBlockHalf - 4 May, 2024
6. Nicehash - 31 May, 2024
7. CoinmarketCap - 1 June, 2024
8. CoinWarz - 3 June, 2024
Now, today on 25th April 2023 after 10 months, this is what these websites say:
1. BuyBitcoinWorldwide - April 6, 2024 (+4 days)
2. Binance Academy - 30 April, 2024 (same)
3. Gate.io - 28 April, 2024 (-5 days)
4. CoinGecko - 28 April, 2024 (-6 days)
5. BitcoinBlockHalf - 27 April, 2024 (-7 days)
6. Nicehash - Website Down
7. CoinmarketCap - Page Removed
8. CoinWarz - Apr 27, 2024 (-35 days)
If we take an average date from these results, it will be 27-28th April 2024. Let's see how this goes in the future.
