When Golden Week is over.

[Haibel]

I am new to japanese culture, but is golden week like a week that Japan just takes off? My manga was pushed back a week. Also what are these letters he sends?

The way I understand golden week. It's not a week long holiday, But a week of a bunch of holidays.
I work for a college, instead of taking federal/state holidays during the year we take them all in December
and are off for like 3 weeks. It's kinda like that except on a national level. " I Think"
