Hi @SwethaM1 , You can create a calculated metric from a free-form table by dropping the target date into the table, select the time you want to compare traffic against the target using compare time periods feature as shown below

Here is a calculated metric example of today vs yesterday % change in visits. However, I will consider using full-day traffic for accurate comparison in traffic change. For example yesterday compared to the previous day.


Here are some useful resources
