Layoff notice, what does the 60 days mean?

Our team was told about a closure date that is 25 weeks away. I have read a lot of threads here and could not find my exact situation. I do not know if I should start looking now or wait for severance news. What did the workforce office offer?

Start your search early. I wish I had begun the day of the notice.

Write down key dates and keep copies of the notice. Mine helped when a question came up later.
