class quantlab.enums.constant.Date

Bases: object

Sentinel date bounds meaning “no lower bound” and “no upper bound”.

A factor or dataset whose config leaves start_date or end_date unset is given these values, so a date filter always has two concrete endpoints to compare against.

Examples

>>> Date.START_DATE, Date.END_DATE
('1900-01-01', '2100-01-01')
