Siblings Day is a holiday organised in honour of the relationship of brothers and sisters.

On 31st May NOE decided to organise a social media campaign (facebook, instagramm, twitter etc.) asking all NOE members to share a photo in which he or she can be seen together with brothers and sisters. The photo could be taken anywhere, the main message was spending the time happily together.
Two favourite hashtags were applied during the one-day-campaign: #Siblings Day and #I love my borther/sister. Of course, personal messages or short stories could also be added to the post. Even a profile photo could be generated by adding a new photo frame with the message: I♥my brother(s)/sister(s).
NOE achieved a Facebook reach of almost 11.000 people with the Siblings Day campaign.
