Hey, I'm a current Graduate Accelerated Year 1 RVC student. Year 1 (whether for the 4 year or 5 year program) usually starts the last week of September as "Freshers Week" (more of an orientation week with social events, lectures start the following week) and ends after the 3rd week of June (so for me, this is September 26 2022 - June 23 2023).
Winter Vacation is for 3 weeks (2 weeks of December + 1 week of January). Spring Vacation is for 6 weeks(!!!) starting from the 2nd week of March, but you are expected to complete your lambing AHEMS for at least 2 of these weeks. Spring Term lectures start last week of April and go until 3rd week of May. It's pretty much 3 "Dead weeks" from there until Finals during the 2nd and 3rd week of June.
The official 2023-2024 Term Dates haven't been released yet, so it is possible (although unlikely, as they made some pretty big changes to the Year 1 schedule just last year) that something could change, but you should be notified via email when they are released. I can also PM you this year's schedule if you want to see the schedule above visually, too.
If you want to see when exams roughly are, click on whatever program you applied to in the "Exams Timetables" tab on
