What is the difference between YTD and YOY?

For example, the key difference between YOY and YTD is that YTD helps calculate growth from the beginning of the year, calendar or fiscal, until the present date. On the other hand, YOY calculations can start from a specific date. They also compare the numbers with those from the year earlier.
