What happens if today's match is washed out?

I remember during the World Cup, several matches were abandoned due to rain, and points were shared. So yes, it depends on the format — leagues share points, knockouts often have a reserve day.

If a cricket match is washed out due to rain with no play possible, it’s declared a “No Result”. In league stages, each team usually gets 1 point. In knockout stages, the team with a higher group-stage ranking or reserve day rules applies, depending on the tournament regulations.
