abstract = {<p style="text-align: justify;">Let $f$ be an $H$−periodic Hölder continuous function of two real variables.
The error $||f −N_n(p;f)||$ is estimated in the uniform norm and in the Hölder norm,
where $p=(p_k)^∞_{k=0}$ is a nonincreasing sequence of positive numbers and $N_n(p; f)$ is the $n\rm{th}$ Nörlund mean of hexagonal Fourier series of $f$ with respect to $p=(p_k)^∞_{k=0}$.</p>},
