Mercari Advent Calendar 2023 is coming up!

Hello! I’m @yasu_shiwaku of the Mercari Engineering Office.
We have our annual Advent Calendar blogathon event in December every year and we’ll be hosting it again this year!

We have both Mercari and Merpay/Mercoin Advent Calendar at the same time, so please check out Merpay/Mercoin side as well.

What is the Advent Calendar?

The original meaning of Advent Calendar is "a calendar that counts down to Christmas". Based on this custom, Advent Calendar is a public blogging event where people post a blog every day from December 1 to 25.

We’ll be sharing our knowledge of the technologies used by our engineers at Mercari group. We hope this Advent Calendar will help you to enjoy the days leading up to Christmas.
