You can find the daily transaction from http://etherscan.io/chart/tx . Right mouse click and view source, and you will find the following type of data:
data: [ {y : 8893, dt : 'Thursday, July 30, 2015', difficulty : '0.121 TH', estHashrate : '23.7569 GH', blockTime : '4', blockSize : '644', blockCount : '6912', unclesCount : '1299', newaddress : '9205' },
...
,{y : 42581, dt : 'Sunday, June 12, 2016', difficulty : '47.368 TH', estHashrate : '3454.4512 GH', blockTime : '14', blockSize : '1463', blockCount : '6064', unclesCount : '468', newaddress : '2117' },
]
42,581 is the number of transactions for Sunday June 12, 2016.
If you want to try and find the transactions in each block, you can use this script in Common useful JavaScript snippets for geth .
You will see in the script that to find a block, use
var block = eth.getBlock(i, true);
And to find the list of transactions in the block, use
if (block != null && block.transactions != null) {
block.transactions.forEach( function(e) {
if (myaccount == "*" || myaccount == e.from || myaccount == e.to) {
console.log(" tx hash : " + e.hash + "\n"
+ " nonce : " + e.nonce + "\n"
+ " blockHash : " + e.blockHash + "\n"
+ " blockNumber : " + e.blockNumber + "\n"
+ " transactionIndex: " + e.transactionIndex + "\n"
+ " from : " + e.from + "\n"
+ " to : " + e.to + "\n"
+ " value : " + e.value + "\n"
+ " gasPrice : " + e.gasPrice + "\n"
+ " gas : " + e.gas + "\n"
+ " input : " + e.input);
}
})
}
The block timestamp will be in:
block.timestamp
Here's some sample geth
JavaScript code to get your data:
> var i;
undefined
> for (i = 1696781; i < 1696785; i++) {
.. var block = eth.getBlock(i);
.. if (block != null && block.transactions != null) {
...... console.log(i + " " + block.timestamp + " " + block.transactions.length);
...... }
.. }
1696781 1465823661 6
1696782 1465823697 8
1696783 1465823704 5
1696784 1465823718 7
undefined
The block.timestamp field is a Unix timestamp, so 1465823718 = GMT: Mon, 13 Jun 2016 13:25:16 GMT.
You can also try using the JavaScript API - web3.eth.getBlockTransactionCount function:
> var i;
undefined
> for (i = 1696781; i < 1696785; i++) {
.. var block = eth.getBlock(i);
.. var txcount = eth.getBlockTransactionCount(i);
.. console.log(i + " " + block.timestamp + " " + txcount);
.. }
1696781 1465823661 6
1696782 1465823697 8
1696783 1465823704 5
1696784 1465823718 7
undefined
