Hi @jenniferisasi ! Thanks for the changes. If possible just change the names of the months to initial caps... The rest is fine

[jenniferisasi]

Thanks @DanielAlvesLABDH, I should have paid more attention to that. I'll update since I just got word of an additional presentation.

Just used the PR to fix a typo and some placenames in French (other than the what this PR was about). I'll review (myself) only if you are ok @jenniferisasi (so that you can merge) because my updates dismissed Daniel's review

[jenniferisasi]

I need someone to approve this :)

[spapastamkou]

I updated the branch but now the build fails, I am afraid you have to wait until #1994 is merged for this to be fixed @jenniferisasi

[spapastamkou]

you only need to check the previews and, if all is ok, you can merge @jenniferisasi

[acrymble]

@jenniferisasi I think this needs merging
