Purchasing behavior subcategories include Buyer Profiles, Clothing, Food & Drink, Health & Beauty and a lot more. Within each broad subcategory, you can drill down into types of behavior; for example, choosing Buyer Profiles will then let you target DIYers, Fashionistas, Foodies, etc.
Facebook shows how many user profiles you can target in each subcategory, based on their aggregated, multi-sourced offline transaction-based data (or in simpler terms, the number of Facebook users in that category they've matched to offline purchasing data).

But, according to the type of businesses or campaigns you manage, selling to audiences experiencing certain major life events it ́s a Facebook ad targeting option to consider. Moving services, for example, want to get in front of you if you've just purchased a new house or apartment. Wedding photographers target people who are engaged. Facebook has pretty much every conceivable life event targeting option, since we tend to post these to our timelines.

The date ranges possible are 3 months, 6 months and one year.
