is there many festivals or holiday abroad like China? for example Spring Festivals?
many but no more than 365 festivals.
In many Western countries, there is a major holiday covering the Christmas to New Year period, from 25th December [Christmas Day in most Western countries] to 1st January [New Year's Day]. Many workplaces close down or operate at a reduced level during this period.
There is an extended week-end at Easter, a religious festival celebrating Jesus Christ's death and resurrection. The date is determined by the lunar calendar, and varies from year to year, falling in the period from late March to late April, usually in the first half of April.
In addition to these, many Western countries have other days which are public holidays, and these vary between countries. In England, the first and last Mondays in May, and the last Monday in August, are taken as 'Bank Holidays'
