What day is it?
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.
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)
It's the 31st of March, 2019 AD. Judging by the display on PSE, April 1st has never been closer.
