Save all dates to a database

Hi All
I must say this forum is really the most amazing place to find useful stuff every day for me. However there is a small issue that continues to evade me - is it possible to save 365 data points (the next 364 days) by default to the database for use? It would be dynamic 365 days starting current date
PS - I thought about the repeating group solution but wasnt able to save in any “elegant” fashion
