I have daily data of user, and I need to calculate features like first 7 days, second 7 days or last 15 days of the month. The data contains many year so I need to use training_window to calculate for each month. However, the training window doesn't have month unit, only days so I can't do it (since the months have different days) I hope feature labs could consider my idea to update month unit for training window.

Thank so much!
