There will be posts named Monthly and Weekly and i will need to seperate them. ex. Monthly Pisces Horoscope / Weekly Pisces Horoscope. 2 menu on site Weekly and Monthly. Nothing to do with archives, archives should work the proper way.
How to do it? Create 2 post type? Nested something? Any other way?
For zodiac signs i think i will list them under Zodiac Signs taxonomy with thumbnail and date fields is ok.
How can i achieve this and which extensions from metabox will be good to have.
The monthly horoscope and weekly horoscope might have different content so I think you should create two custom post types to separate them. Use the extension MB Custom Post Type to create the post types easily, get more details on the documentation https://docs.metabox.io/creating-post-types/.
