When you have an online sales activity, it is of course essential to know the most favourable periods to sell.

Knowing these dates will help you know who and when to target when launching your advertising campaigns.

If you know in advance that Valentine's Day is on February 14th, you can plan as early as January to design products around the lovers' day and to put them forward on your website as well as on your advertisements.

Whether you are European or American, we have prepared a small list of must-know dates to help you increase your sales on your site.

This is as complete as possible, but depending on the country you are targeting, some national holidays may not be included: be creative and target specific festivities that your competitors have not thought of.

Whether you use Etsy, Shopify or WooCommerce for your e-commerce site, don't hesitate to highlight these dates on your online shop.
