The NIH limitation is by council round, rather than submission date. Council rounds can be found on the NIH standard due dates page: https://grants.nih.gov/grants-process/submit/submission-policies/standard-due-dates
Here is the policy info on the limitation:

Some additional guidance (including a table to show which deadlines fit into which year) can be found on the OSP website: https://research-support.yale.edu/sponsored-projects/office-of-sponsored-projects/proposals
