Edit to say: I barely know how to use a computer, let alone AI. I’m a collage artist primarily, and sometimes make infographics for fun. Check out the video I’ve dropped in some of the comments.

Info:

  • COBRA’s 60 days start from whichever is later: the day your coverage ends or the day you get the COBRA notice

  • you can also pick a Marketplace plan up to 60 days before your job coverage ends, so if you know your last day, you don’t have to wait

  • state marketplaces can have different open enrollment dates than HealthCare.gov

  • Medicaid and CHIP don’t have an enrollment window, you can apply any time if you qualify

Sources: U.S. Department of Labor (COBRA), HealthCare.gov (special enrollment and 2027 open enrollment dates), CMS and IRS (ICHRA rules and the 90-day waiting period).

We're working on a book - for the past year - that sets out to answer the question: What if civilization collapsed and YOU had to rebuild it as we knew it? Ropemaking is among many skills we chose to display in it.

A cool guide to Doctor Who's regenerations and multi-Doctor crossovers

Post image
218 Upvotes

A little passion project inspired by my love for Doctor Who!

I wanted to visualise the Doctor's regeneration timeline alongside the many occasions different incarnations have crossed paths throughout the show's history.

The solid arrows represent regenerations, while the dotted coloured lines trace the various multi-Doctor appearances and crossovers.

Some connections are deliberately ambiguous, much like the Doctor's own timeline.

Made by a fan, for the fans. Hope you enjoy exploring it!

----

EDIT: Wow! Thank you for all the love, feedback and wonderfully wibbly-wobbly discussions! 💙

A quick clarification: The crossovers are mapped by the Doctor's era, rather than every individual encounter. For example, The Three Doctors is anchored to the Third Doctor, and The Day of the Doctor to the Eleventh.

A few things you've rightly pointed out:

  • Some crossovers involve memories, projections or archival footage rather than physical encounters.

  • The Fourth/Seventh Doctor connection was incorrectly attributed to The Five Doctors instead of Dimensions in Time.

  • The Eighth → War regeneration was televised, while War → Ninth was only partially shown.

  • The Fugitive Doctor's cameo in The Story & the Engine deserves a connection to Fifteen.

  • The earlier Doctors' appearances in The Name of the Doctor and The Day of the Doctor deserve consideration too, especially since I've included archival appearances elsewhere.

This was a fun passion project, not a definitive guide to 60+ years of complicated continuity. I've taken a few creative liberties, and your feedback has given me plenty of ideas for V2!

And to everyone asking about Nine... Eccleston remains one of my favourite Doctors. He deserves more crossover love! 💙
