Nothing ever happened in the past; it happened in the Now.

Nothing will ever happen in the future; it will happen in the Now.

What you think of as the past is a memory trace, stored in the mind, of a former Now. When you remember the past, you reactivate a memory trace and you do so now.

The future is an imagined Now, a projection of the mind. When the future comes, it comes as the Now. When you think about the future, you do it now.
