The journal's editors are on Christmas break.
The editorial departments of some SCI journals will stop reviewing manuscripts during specific holidays, such as Christmas. This is because Christmas is regarded as the Spring Festival in the United States, and editors will use this time to take a vacation.
Therefore, when submitting your article, you can check whether there is a holiday in the country where the magazine belongs. It is worth noting that in addition to Christmas, the months after the summer vacation and before Christmas are also the peak periods for reviewers to review manuscripts.
