Um, just a little comment on the time zone maps.
It seems that the map is using DST for some countries that might not be in it in April.
Just remember that, wherever you are, if you know that DST is not active anymore, take out the extra hour the map is adding. For example: Brazil is not on DST in April (ends in February), so the Kerth ceremony will be at 7:00 PM local time Sao Paulo, not 8 as the map shows.
