Hereâs what I have on Royal Portables: late 60âs NOMDA Line Book, Royal Portables. As you can see, this list is slightly confusing as well, with the first column showing serial numbers from 1926 to 1956, and a second column with a different set of serial numbers between 1932 and 1942.
The statute actually says six days in a calendar week is the maximum permissible time worked. The 12-day limit arises if an employee is required to work the last six days of one week and the first six days of the following week. Thatâs 12 consecutive days, but still no more than six days in a calendar week.
By doing this, you can determine how many days your cycle is from day one to day one of the next period. Do this for each cycle, then average the numbers. For example, my last four cycles were: Cycle One - 29 days, Cycle Two - 31 days, Cycle Three - 31 days, Cycle Four - 30 days. Add up the number of days, divide by 4 months, and you get an average of 30 days. With that number, you can predict the first day of your next period when adding 30 days to the last. So, if my last period started on February 2, I add 30 days and come up with March 4 for the first day of my next period.
