TODATE (DayIndex)

Description

This function shows the name of day for the given Index number.
In $TODATE(DayIndex)$ , $DayIndex$ is the any number from 1 to 7.
The names of the 7 days of the week in most Latin-based languages come from the Roman calendar, which related each day with 7 celestial bodies considered to be gods: the Sun, the Moon, Mercury, Venus, Mars, Jupiter, and Saturn.
The 7-day-week provides a clear method of representing dates and times to avoid misinterpretation between people from different countries with varying traditions for writing numeric dates and times.
According to the international standard,Monday is the first day of week.
Although this is the international standard, several countries, including the United States, Canada, and Australia consider Sunday as the start of the week.
So in this function first day of the week is considered as SUNDAY.
Second day of the week is MONDAY and so on.
This function will return the result as error when the parameter value is other than 1 to 7.
