From November 21, non-essential activities will have to stop between 10 p.m. PST to 5 a.m. PST in counties in the purple tier. The order will remain in effect until 5 a.m. on December 21, though it could be revised or extended.

This means that all gatherings with members of other households and other activities outside of the residence have to stop.

The order does not apply to activities relating to the operation, maintenance, or usage of critical infrastructure, to activities required by law. Additionally, the order does not apply to people experiencing homelessness.

People from the same household can still leave their homes between these times as long as they do not engage in any interaction or gather with anyone from outside of their household.

Erica S. Pan, Acting State Public Health Officer of the California Department of Public Health, explained the reasoning behind this curfew in a news release and said: “This Limited Stay at Home Order will reduce opportunities for disease transmission with the goal of decreasing the number of hours individuals are in the community and mixing with individuals outside of their household.

“Every intervention to decrease mixing of households is critical during this unparalleled increase in case rate rise of about 50 percent during the first week in November.

“In particular, activities conducted during 10 p.m. to 5 a.m. are often non-essential and more likely related to social activities and gatherings that have a higher likelihood of leading to reduced inhibition and reduced likelihood to adhere to COVID-19 preventive measures (e.g., wearing face coverings and maintaining physical distance).”

Data from November 18 shows that California has had 1,059,267 cases and 18,466 deaths related to COVID-19.
