Days played resets each time I load world

Hello, I was playing my world in Minecraft, but I have seeing a bug, it doesn't matter how many days I play in that world, every time I get out and enter again, it shows 33 days at sunset, but I counted and I am playing for much time than 90 days, could you please show me how I concert this bug? I want see my actual days played. (Sorry if my English is bad 😞).
