Translating Rules from Apache to Nginx

I have switched server from Apache to Nginx.

Everything works, except for the last bit.

In Apache I have the following rules:

RewriteRule ^event/(.*)$ /event.html [L]
RewriteRule ^/event/(.*)$ /event.html [L]
RewriteRule ^venue/(.*)$ /venue.html [L]
RewriteRule ^/venue/(.*)$ /venue.html [L]
RewriteRule ^calendar/day/(.*)$ /calendar/day.html [L]
RewriteRule ^/calendar/day/(.*)$ /calendar/day.html [L]
RewriteRule ^calendar/month/(.*)$ /calendar/month.html [L]
RewriteRule ^/calendar/month/(.*)$ /calendar/month.html [L]

But can't get them right in Nginx. The following is the implementation:

location /event {
  rewrite ^/event/(.*)$ /event.html break;
  rewrite ^/event/(.*)$ /event.html break;
}

location /venue {
  rewrite ^/venue/(.*)$ /venue.html break;
  rewrite ^/venue/(.*)$ /venue.html break;
}

location /calendar {
  rewrite ^/calendar/day/(.*)$ /calendar/day.html break;
  rewrite ^/calendar/day/(.*)$ /calendar/day.html break;
  rewrite ^/calendar/month/(.*)$ /calendar/month.html break;
  rewrite ^/calendar/month/(.*)$ /calendar/month.html break;
}

But I get redirected to the Home Page when the above are accessed.

Can someone help me please?
