Line 146:
Some other language implementations are using Zeller's congruence, too, so those may have the same problem.

=== TeX formula ===
<math>\begin{align}
adjustment = & \lfloor (14 - month) \div 12 \rfloor \\
mm = & month + 12 \times adjustment \\
yy = & year - adjustment \\
weekday \equiv & day + \lfloor (13 \times mm + 8) \div 5 \rfloor \\
& + yy + \lfloor yy \div 4 \rfloor
- \lfloor yy \div 100 \rfloor
+ \lfloor yy \div 400 \rfloor \mod 7 \\
\end{align}</math>
I wrote this [[metawikipedia:Help:Formula|TeX formula]] for Zeller's congruence, but decided not to put it on the page, so I saved it here. --[[User:Kernigh|Kernigh]] 21:43, 11 November 2011 (UTC)
