Thanks for joining the thread, @twcw4.
I'd love to help you achieve your goal, but would you mind sharing more details about the hours you want to get based on the anniversary date? Are you trying to create a report or setting up the hours? It can help us get on the same page and provide accurate resolution.
I'll wait for your reply, or if you have any other questions, please let us know. We're always here to help. Have a great day.
