The Aztecs had two types of calendars.
The first is the scared calendar known as the Tzolkin. It combines the numbers from 1 through 13 with a sequence of 20 day-names. It works in a similar manner to our named days of the week, and their date within each month. So you might have 5-Chikchan (like our Sunday the 5th) followed by 6-Kimi (as we would have Monday the 6th). After 260 days the same number/name combination will re-occur, and the calendar starts anew. Their use of the vigesimal (base 20) numbering system probably relates to fingers and toes, whereas the 13 nicely fits the growth phase of the moon which isn't visible when new and appears full for two days on end, thus appearing to have a 13 day growth cycle. Alternatively, the length of the Tzolkin may be related to the human gestation period of nine months (273 days). It has been suggested that 260 days is the time between a woman suspecting her pregnancy (she doesn't menstruate) and when she gives birth.
The second is the agricultural calendar known as the Haab, or vague year. It consists of 18 months, each of 20 days. An addition of a five-day month (a period of apprehension and bad luck named Uayeb) gives us 365 days, an approximation of a year. This calendar's primary purpose was to keep track of the seasons, for seasonal and solar events would occur on roughly the same day of each year. The Maya were aware of the annual quarter day discrepancy, but it is not known if they ever did anything about it.
These two independently running calendars each begin again every 260 and 360+5 days. However, every 52 years they coincide.
By looking at what position the sun was at.
ancient people like Romans use sundials water clock (clepsydra), and calendar

The individual who should keep track of attendance in the workplace or office should be the supervisor or manager. In most offices there is some way for employees to clock in, be it a time clock or electronically through there computers. If this system is not in place then it becomes the duty of the Supervisor to supervise his peoples coming and going.
