Description
- Description:
- Convert a date to a float number, based on Jan 1st 00:00:00 = 0 and Dec 31st 23:59:59 = 1. The same day and time in leap year will be different after 28th of February and 23:59 on 31st of December will be 1.00274
This is how this command works. The 365 days of the year are presented in range 0...1. So each day will be:
1/ 365 0.00273973
In a leap year there are 366 days, so the range will increase by 1 day:
1/ 365 * 366 1.00274
In short, in a normal year the command returns in range 0...1 in a leap year it will return in range 0...1.00274 - Groups:
