There are so many Holidays, Events and Observances in a year. Work ahead plan it out and submit 2 month before the date.
Those company like advertising agency, design house and printing company will desperately need all those image stock for their project. For your reference, here's some major events of the year:-
- New Year celebration (31 Dec)
- Chinese/Lunar New Year (mostly Jan or Feb of the year)
- Valentine's Day (14 Feb)
- Mother's Day (11 May)
- Father's Day (15 June)
- Halloween (31 Oct)
- Thanksgiving (27 Nov)
- Christmas (25 Dec)
Don't forget to prepare image stock for birthday too. There's a new born baby every day in this world, so every day is a birthday for someone out there.
Btw, my Chinese New Year image stock (illustrations) is sell like a hot cake last month/year :)
