Lambda Days
is a one of a kind experience in the functional world.
10-11 February 2022
Kraków | Poland

Lambda Days is a place where academia meets industry, where research and practical application collide.

Find out what is possible with functional programming - explore the latest in battle-tested Scala, Erlang and Haskell, experience the energy F# and Elixir bring to the table, connect with the innovators working with Elm, Luna and Ocaml, see what comes up next!

For the third time we join forces with Trends in Functional Programming (TFP) who will be running two dedicated tracks, showcasing the latest academic research on functional programming. Moreover, this year Trends in Functional Programming in Education (TFPiE) will be running at the same venue on Friday 11th, creating a 4th track on that day on teaching FP.

To make sure everyone felt safe and comfortable, two Lambda Days tracks will be run a HYBRID tracks, combining both an in-person and virtual experience. Read more about it here.

In person tickets

Virtual tickets


As always we’re doing our best to make sure our conference is as diverse and awesome as the community we serve.

Thanks to the support from Standard Chartered we can distribute 5 in-person tickets and 10 virtual tickets among participants from groups underrepresented in IT.

Apply to get yours!

First deadline: 21/01/2021 (recipients chosen)

Second deadline: 01/02/2022 (if recipients do not confirm, tickets are redistributed)

Call For Talks

Are you interested in presenting your thoughts on the subject of functional programming? Submit your presentation!

As of now we have identified 6 areas our audience would love to hear about:

Functional languages
Software and system design
Reactive Programming
Web programming
Computation in functional technologies
Applications and case studies

Is your presentation slightly outside that scope? Amaze and inspire us with your submission!

We’re happy to support candidates from under-represented groups in the software development community.

If you have not spoken at conferences before or need help in preparing, our programme committee members are happy to mentor and assist you with their feedback in the planning and delivery stages of your talk.

The first round of reviews will take place in October. The second round in November can be cancelled if we receive enough submissions in the first round.

Call For Papers - TFP and TFPiE

TFP and Lambda Days take place on February 10-11th and TFPiE takes place on February 11th at the same venue. There is one ticket to all 3 events/tracks and one registration. For TFP and TFPiE speakers/presenters the tickets are complimentary, no need to purchase. TFP and TFPiE tracks will not be streamed.

23nd International Symposium on Trends in Functional Programming

The symposium on Trends in Functional Programming (TFP) is an international forum for researchers with interests in all aspects of functional programming, taking a broad view of current and future trends in the area. It aspires to be a lively environment for presenting the latest research results, and other contributions.

More information can be found HERE.

Submission deadline for pre-symposium review: 1st December 2021.

Submission deadline for draft papers: 12th January 2022.

International Workshops on Trends in Functional Programming in Education

TFPIE welcomes submissions describing techniques used in the classroom, tools used in and/or developed for the classroom and any creative use of FP to aid education in or outside Computer Science. After the workshop (11.02), presenters are invited to submit (a revised version of) their article for review. The PC will select the best articles that will be published in the Electronic Proceedings in Theoretical Computer Science (EPTCS).

More information can be found HERE.

Submission deadline: 5th January 2022.


Why should you attend Lambda Days 2022? (a.k.a. "why can’t I just watch the talk videos online for free instead…?")

Firstly, not all the videos will be published right after the conference and will be kept exclusive to the attendees for a couple months.

The greatest asset of any conference is the community behind it. The Lambda Days crowd is inquisitive, open-minded, friendly and known to motivate each other to learn and innovate.

They ask the right questions, recommend the best talks, point to concepts to explore, inspire and challenge preconceptions at every turn.

Going hybrid

February is coming close and though the pandemic situation is not yet fully contained, we’re optimistic to meet with you in Krakow and we will make sure not only to deliver a great experience, but also that it’s delivered in a safe environment. However, we’re also keeping in mind that by then not everyone will be able to travel, therefore, we’ve decided to make Lambda Days a hybrid event, combining both an in-person and virtual conference.

There will be two different categories of tickets going on sale at the same time - for the in-person conference (Lambda Days, TFP and TFPiE) and for virtual conference attendance (Lambda Days two tracks through two days).

Trends in Functional Programming and Trends in Functional Programming in Education will not be a part of virtual experience.


Your safety and the safety of others is of the utmost importance to us as organisers. All attendees must present one of the following:

  • A negative COVID test dated no more than 72 hours prior to the conference (both quick test and PCR test are accepted)
  • Proof of vaccination (either in writing, on a card, or on the mObywatel app - QR code)
  • A waiver form signed a day prior to the conference via conference app or signed on paper on the day of the conference. 

Do not attend if you or anyone you have been in contact with has shown any symptoms of COVID 72 hours prior.
