by their nature the days of the week by name are neither even or odd. The numerical day of the month a day falls on can be either even or odd. Note that a month with 31 days will have an odd day at the end of month followed immediately by another odd day. This never happens for even days.

The Jews observe Saturday as their sabath, so the first day of the week falls on Sunday.
To determine the first weekend of the month, start by identifying the first day of the month and then find the nearest Saturday or Sunday. If the first day is a Saturday, that day is the first weekend. If it’s a Sunday, the previous day, Saturday, is considered the first weekend. If the first day falls on any other weekday, the following Saturday will be the first weekend.
