What day is it?

• Sounds like the plot to a Nolan WWII film. – Don Thousand Mar 31 at 13:00

To explain

where the mapping found in Bass's answer comes from

note that

each of the things listed has an official Day named after it, and the alphabet positions are the day-of-month numbers. E.g., Hiroshima Day is the 6th of August, Youth Day (according to the UN; some countries have their own) is the 12th of August, and Nelson Mandela Day is the 18th of July. Hence F, L, R respectively.

• Nice, that's what I thought too. Did you manage to work back from the solution to figure out which country's army we were supposed to celebrate? (I gave up with the googling at that point, because the time zone of the question didn't line up with the solution in a very sensible manner for any of the possibilities.) – Bass Mar 31 at 20:42

• @noedne beat me to it — Army Day is Jan 15th in India. – El-Guest Mar 31 at 20:56
• I didn't try, I'm afraid, I just checked enough to be sure I was right :-). The correspondence described here is what I thought of instantly when I saw the puzzle several hours ago -- but I looked up one of them and it didn't seem to work out, so I didn't post anything. Then I came back here, saw @pirate's comment on your answer, and gave it another go. The thing that confused me wasn't the army one but the Post Office; it turns out that the first thing I found was nonsense. – Gareth McCaughan Mar 31 at 21:07

It is

April Fools.

Because

 Post Office    = I
Refugee        = T
Post Office    = I
Photography    = S
Milk           = A
Food           = P
Nelson Mandela = R
Post Office    = I
Youth          = L
Hiroshima      = F
Army           = O
Army           = O
Youth          = L
Photography    = S

(A simple substitution cipher)

• Yeah that's right, but the words aren't random (hint in title) – pirate Mar 31 at 19:16
• @pirate, Given that they require detailed knowledge of miscellaneous days celebrated in more or less random countries around the world, they might as well be. :-) – Bass Mar 31 at 23:32

It's the 31st of March, 2019 AD. Judging by the display on PSE, April 1st has never been closer.

• @pirate It is a joke answer, in the spirit of April 1st. If it is not welcome, I will delete it. – Arnaud Mortier Mar 31 at 16:43
