Ramadan?

So.....Tomorrow is Ramadan, the month when Muslims fast. Mumkin (maybe) it is tomorrow (in sha allah). The most we've been able to get out of our teachers is that it is either tomorrow or the next day (possibly depending on the moon?). This means that we will not be able to eat or drink (even water), or smoke in public for 30 days. Nothing opens before noon, and grocery stores won't open until an hour before sundown. At sundown people pray then drink some water and eat some dates then party like it's 1999 till dawn. It is not the law here like it is in Kuwait, however I'm sure we would not be looked upon fondly if we were to eat during the day. Looks like I might be smoking a lot less of those $.75 a pack cigarettes.
