I am against the idea of postponing the tournament because of a holiday. I will explain why.
First, each registered team, each player participating in the tournament, before submitting the registration, read the rules of the tournament, the dates of its holding and agreed to the terms and voluntarily registered or registered his team. Dates and times of tournaments are scheduled for months in advance. To change the tournament schedule for the sake of one holiday is stupid. All the more to change the schedule of the tournament at the request of one person to undermine not only the schedule of the first league, but also the second.
Secondly, for this purpose and was added from eight players to the team, so that if someone was unable to play, he could be replaced by other players + emergency players. If someone will be celebrating and resting during this time - no problem, this player can simply be replaced, as the tournament will be five against five, and each team has eight players - so I do not see the point of postponing the tournament.
