Demon Dantalion is described in the Goetia quite exactly and below you will find useful information about this spirit. Hopefully, this information will help you to summon Dantalion.
Demon Dantalion: Goetia
Dantalion is the 71st spirit and he is ranked as a Duke. He shows up in the form of a man with many faces (all men’s and women’s faces) and he holds a book in his right hand.
Dantalion can teach you any arts and sciences and he will also declare to you the secret counsels of any person. Dantalion knows the thoughts of all men and women and he can change them as he desires.
This spirit can cause love. Finally, Dantalion rules 36 legions of spirits.

Dantalion: my magick
I have done magick with Dantalion to help my clients who had difficult family relationships. Dantalion helped to mend broken communication and helped to smooth out the pain of past experiences.
Dantalion can help to tame angry animals too. I have done magick with Dantalion on my cockatoo to stop his vicious biting. I summoned Dantalion together with Barbatos to chill out my pet’s anger towards me.
Barbatos taught me the language of cockatoos very quickly. Dantalion made my bird fall in love with me and we bonded on a soul level.
The magick was a bit overdone, because today my cockatoo is glued to me. He wants to be with me all the time.
Demon Dantalion: when to summon him?

Dantalion is ranked as a Duke and he comes from Harab Serapel. All the Dukes of Goetia come from Harab Serapel. If you know the Tree of Life and its 10 Sephiroth, then Dantalion comes from Netzach.
I use the correspondences of Netzach even for Harab-Serapel:
Ruling planet: Venus
Day: Friday
Astrological hour: Venus
Paper seal colour: green
Metal seal: copper
Number: 7 (7 items, for example 7 roses or 7 toys for pets)
Herb: cinnamon (my own choice)
Scent: sandalwood
The best day for rituals with Dantalion is Friday. You can do magick with Dantalion during the waxing moon and also during the full moon. If you want to fine tune your magick, then aim for the astrological hour of Venus.
