Hi everyone,Happy New Year!
I use the events guide in the Buddhist Society of Victoria, if you scroll through them you'll find certain days, it's typed in red under the date, and lets you know if it's a full moon or new moon.
I also downloaded the one Alobha gave,but some of the dates didn't match, it was a day later.So maybe this only works if you live in Australia.???
sorry,i'm new to this.Will start to observe Uposatha days this year!!
