Dear Jürgen Weippert What you said is not entirely correct. The JCR Report 2024 will indeed consider the citation/impact factor data of (a calendar year in this case) 2023. This report is always released (they take a few extra months to ensure that they have all available info related to 2023 this way) somewhere in June.
See https://clarivate.com/blog/2024-journal-citation-reports-changes-in-journal-impact-factor-category-rankings-to-enhance-transparency-and-inclusivity/ where they state and I quote "Our commitment to enhancing transparency and trust continues in the forthcoming JCR release in June 2024."
Best regards.
PS. Atallah Al-Shammary hopefully someone is able to provide the complete JCR Report this year. No one has unfortunately been able to release the JCR Report 2023 here on RG last year. I guess Clarivate has successfully protected their 'property' (while the years before 2023 there where numerous editions publicly available).
Dear Muhammad Nadeem Zafar The following link announced that June 20th is indeed the release date https://clarivate.com/news/clarivate-reveals-worlds-leading-and-trusted-journals-with-the-2024-journal-citation-reports/
