basically, there are two possible approaches:

1.  you can query task list and search for single approval tasks and then perform needed calculations. you will to properly configure task name or task description so that you are able reliable identify them.

2. add a (hidden) columns to your list and maintain respective dates on your own.

I would personally go for opt.2 since you have more control over it and it allows you to calculate it directly in list view, if needed.
