Hey, I checked out your blog. You are a really talented photographer. The schedule for the contests the @czechglobalhosts runs is:

Australian Monday
Antarctica and World's Oceans Tuesday
African Wednesday
European Thursday
North American Friday
South American Saturday
Asian Sunday

I am looking forward to seeing some of your on Asian Sunday, unless you have traveled outside of Bangladesh as well, then you can enter those pictures on the day of where you have traveled. On Tuesday you can enter you pictures of the ocean, and I am sure you will be able to get some really cool pictures there in Bangladesh. Keep up the good work.
