Ar lefel rhybudd sero, ni fydd unrhyw gyfyngiadau cyfreithiol ar nifer y bobl sy'n gallu cyfarfod, gan gynnwys mewn cartrefi preifat, mannau cyhoeddus nac mewn digwyddiadau. Bydd yr ychydig fusnesau sy'n weddill, yr oedd yn ofynnol iddynt gau, gan gynnwys clybiau nos, yn gallu agor.
At alert level zero, there will be no legal limits on the number of people who can meet, including in private homes, public places or at events. The few remaining businesses, which were required to be closed, including nightclubs, will be able to open.
