koreanfestivals1-3, Exercise 2: Ban and restoration

Model answer (five dated steps):

1. 1907: celebrating Seollal was banned, enacted by Emperor Sunjong under intense pressure from the Japanese (the article's account).
2. From 1910: after annexation the prohibition was reiterated; the official new year followed the Gregorian 1 January (sinjeong) and the old one became gujeong.
3. 1945 to 1950: a provisional government designated 1 to 3 January as a public new year holiday.
4. 1985 to 1988: after widespread public opinion in the 1980s favoured restoration, the government declared Seollal a "folk day".
5. 1989: the Roh Tae-woo administration designated the original new year as both the official Korean New Year and a national holiday.

This fills the gap Chapter 2 flagged: the public holidays article did not explain how Seollal returned as a major holiday, and the Seollal article gives the sequence.
The dates should be checked against a legal source because the article cites no source for them in what I read, and an encyclopedia article is not the decrees themselves.
