Event Info & Rules
DadDecember is an annual prompt month featuring platonic father and child relationships. We have a collection of prompts for each day meant to inspire works to be created.
*Due to the nature of this event being, do not submit father/child incestual content. That is not the point of this event. This event is strictly platonic. Thank you for understanding.
There are 62 prompts this year with 10 alternative prompts. Each day has two prompts, one situational/trope prompt and one dialogue prompt. You do not need to use both. While we do encourage you to mix and match prompts with different days to fit your specific WIP, we do ask that you tag the prompt you used, not just the day.
This is a prompt month meant to inspire works, so please don’t take any of the prompts too seriously! If you want to get silly with it or really angsty, that’s up to you! How much of the prompt you use and how you use it is all up to you! If you think it fits the prompt, then it does. There is no gatekeeping in DadDecember.
It’s up to the creator how much they want to produce or what media form they want to create in! Anything and everything counts (and if you’re really unsure, you can always ask!). The idea of the event is to create, no matter in the manner you do so.
As far as “how much do I need to do in order for it to count?” – Well, that’s up to you! All participants, regardless of how many works they put out, will be recognized for their efforts! A google form will be sent out after December ends in which you will be able to say how many works you completed. Works do not need to be published in any way shape or form to count. Participants will be ranked by completion in a tumblr post after the form closes and a custom role will be available for completionists in our discord server.

Frequently Asked Questions
Q. Do I have to do all 31 days?
Participate as much as you would like! Whether you can get out one piece between now and the end of December or 45, we are here to encourage you all along the way!
Q. Can I post early/late?
Yes, you can post whenever you want. Due to time constraints, we may not reblog posts outside of December (pinging @Mod Addri via discord will always get you reblogged, though, so you can always try that ;) ).
Q. Can I combine DadDecember with other creation challenges?
Yes, as long as the other challenges allow it as well. Please reference their rules.
Q. Can I use prompts to write a new chapter for an existing fic?
Yes.
Q. Can I use a prompt multiple times?
Yes, but it only will count once for your total completion number (unless combined with a different unused prompt).
Q. Do I have to finish a fic I started/can I post WIP’s?
Yes, you can post WIPs. Snippets or other forms of WIPs are completely fine and will still count for completion! As long as you started it, feel free to count it!
Q. Is collaborating allowed?
Absolutely, we even encourage it! Collaborations can be an amazing way to get full completion status (especially if you’re competitive) without as much work! It would count towards being a completionist for both/all of you.
Q. Can I combine prompts? Is there a limit on how many?
No limit and combine as many as you’d like.
Q. Can I start working on the prompts before December?
Absolutely! That’s why we post the prompts a little over a month in advance. We recognise how difficult it can be creating for 31 days in “real time” so feel free to start creating early!
Q. Do I have to use your required tags?
If you want your work reblogged, yes.
Q. Does combining prompts count towards completion?
Yes.
Note: This is a creation challenge, please don’t repost your old work under our tags (unless it’s been changed or edited for the event).
Best of luck,
Mod Addri
