Background As part of the European Research Area vision, the European Commission is aiming to see the necessary transformations in R&I that will include the promotion of citizen science and societal engagement, the mainstreaming of Open Science practices, the fostering of brain and knowledge circulation, strengthening of academia-business collaboration and embodiment in a global Research and Innovation (R&I) ecosystem. The YUFE (Young Universities for the Future of Europe) alliance embraces this challenge in the YUFERING project by effectively contributing to pilot these needed transformations to improve and harmonise the conditions for R&I in Europe. Focusing on key elements of the ERA and in full alignment with the relevant SwafS call for proposals, YUFERING proposes ground-breaking transformation actions that will bring the partners one step closer to creating and realising a shared robust R&I vision, really committed with Open Science. More specifically, WP5 (led by Carlos III University of Madrid) aims to create a YUFE Open Science Strategy and look for a post-COVID-19 approach that states Open Science as ���the new normal��� in YUFE Universities. In this regard, one of the main objectives of this project is the co-creation of a YUFE Open Education Training Suite on Open Science. Under the umbrella of Task 5.4., an informative/formative Open Science Calendar that aims to increase awareness on the Open Science pillars and practices among researchers, has been elaborated. Here we offer a customisable version of the calendar to be used by any institution in the world interested and committed to Open Science. Add your logos, your messages, your services for Open Science and enjoy!!! Please share alike in Twitter your version with the hashtag #YUFEOSCalendar. Resources to customise your Calendar The materials shared will provide you with everything you need to set up your own calendar. All material is created by the Uc3m YUFERING team and the illustrations used and licenses are properly indicated. It includes a PowerPoint file and also a guideline that can help you in the process. Feel free to customize your ad hoc version and enjoy!!! We would be very happy if you share (SA) your results and creativity with the community. Please share your versions of the calendar on Twitter with the hashtag #YUFEOSCalendar at @OpenUC3M or feel free to send an email to us: openscience@uc3m.es
