Greetings friend, thank you for your wonderful words and appreciation for the Steem4nigeria team, I must say you are very much welcome with us. However, I feel you left out something, which is shown below:

Participating time is from 00:00 (UTC) on Monday 19th February to 23:59 (UTC) on Sunday 25th February 2024.

This is to say this contest is yet to kick off just yet at still has over 55 minutes to 0:00 (UCT) Coordinated Universal Time.

Since you're in Ukraine, and the time zone is typically Eastern European Time (EET). The offset for EET is usually UTC+2. So, if it's 0:00 UTC, it would be 2:00 AM in Ukraine. Meaning the contest is only open for entries by 2:00 AM Ukraine time.
