Can You Solve This Math Problem?

Hai, teman-teman... Blog Gifta kok sepi sih? Sudah hampir 1 minggu CBOX gak ada message baru ;_;
Sekarang, Gifta mau memberikan soal Matematika.
Sumber soalnya Olimpiade Matematika Singapura: yang masuk berita di mana-mana. Gifta berikan agar teman-teman dapat ikut menyelesaikan masalah ini!
Kalau mau jawab, lewat form request di laman request, ya!
Oke, CEKIDOT

Greg and Tom just met Pamela. “When’s your birthday?” Greg asked Pamela. Pamela thought for a second. And then she said, “Hmm … I’m not going to tell you, but I’ll give you some clues.” She wrote down a list of 10 dates.
May 15
May 16
May 19
June 17

 “My birthday is one of these,” Pamela said.
Then Pamela whispered in Greg’s ear the month — and only the month — of her birthday. To Tom, she whispered the day, and only the day. 
--- Greg: I don’t know when your birthday is, but I know Tom doesn’t know too
--- Tom: I didn’t know originally, but now I do!
--- Greg: Well, now I know too!

I want to ask you now. When is Pamela’s birthday?
Sorry ya pakai bahasa inggris. Kalau mau bahasa indonesianya, bisa ke google translate :) Sebenarnya soal ini sudah ada di: http://giftagood-blogger.tumblr.com/post/116557219700/hmm-can-you-solve
