Date

Date Input

Data Index Length Type
Day 1 1 Integer
Month 2 1 Integer
Year 3 1 Integer

The input is not affected by the date format, i.e. dd.mm or mm/dd.

# Date Examples

3B 07 80 40 02 01 01 14 EA      # 01/01/2020
3B 07 80 40 02 1F 01 14 F4      # 31/01/2020
3B 07 80 40 02 01 0C 14 E7      # 01/12/2020
3B 07 80 40 02 1F 0C 00 ED      # 31/12/2020
Year Limitation

The only trick is specifying Year as the input is limited to YY, e.g. 15 represents 2015.

This begs the question, with an input of 25, is that 1925, or 2025?

Fortunately we need not worry about this for many decades as the navigation OS software (4-1/00) defaults to years 1993 to 2092.

Input Year
00..92 2000..2092
93..99 1993..1999
