These are real renders from the API with the example values in the table below. Switch the size above: the same template lays itself out for all 6 sizes — send size or sizes with the request.
For communities, schools, creators and productivity apps that publish a content or events calendar. The grid is computed from month and year with weeks starting on Monday and weekday names in the card's language; a month that cannot be read falls back to the current one. Up to six labelled days are listed. Wide frames put the month name and labels on the left of the grid; square and vertical frames stack the name, the grid and the labels.

Every field is optional. Long text shrinks to fit instead of overflowing; an image field takes a public URL that we fetch on our side.
