Autoencoder with specific features in encoded layer

I want to create an autoencoder which will map date + 24 hourly data

for example 25/08/2020 – [25,8,2020,23,3,11,31,43,43,23,23,45,23,11,32,43,52,34,23,12,43,52,32,54,23,54,34]

to encoded layer of 3 features [day, month, year] so that I can predict hourly values out of these.
I am using Keras and I tried different tutorials but I don’t know how to "focus" the model on these date features so later on I could receive an hourly data out of these. Can you please give me hint how can I do this?
