Here you can find the domain to filter on today's date.



['&',
('x_date_start', '>=', context_today().strftime("%Y-%m-%d 00:00:00")),
('x_date_start', '<=', context_today().strftime("%Y-%m-%d 23:59:59"))
]



You can create a user defined filter and add the code in the domain field. Note that you need to adapt the date field name to the field you want to filter on.
