NEW DELHI: Indian Prime Minister Narendra Modi has wished Afghan President Ashraf Ghani a happy birthday — only for Ghani to explain he had got the wrong day, BBC reports.

Modi had tweeted his best wishes to Ghani, writing: “Praying for your long life & exceptional health and a joyful journey ahead.” Later, Ghani gently point out his birthday is, in fact, on May 19.

Ghani’s profile on Google lists his birthday as being on Feb. 12, which may explain the mistake.

It is not known if Modi himself wrote the tweet as most of his tweets are reportedly written by his social media manager, Hiren Joshi.

And it is unlikely Ghani, who is at Munich Security Conference, wrote the polite reply, as any posts written by the president himself are signed AG.

The mistake was spotted by plenty of people. One Twitter user in India wrote: “We don’t care when you b’day is , if our honorable PM has wished you today, we will celebrate it today.”

Another user said it was “the biggest international joke from someone occupying the biggest chair in the biggest democracy.”
