The ascending days [t+] and descending days [t-] day tokens correspond to the ascending and descending counts found in many diaries.
Ascending days equal 1 on the first day of the year. Descending days count the number of days before the end of the year, and are equal to 0 on December 31st.
•To force the displaying of ascending and descending days over 3 digits (ie. 001, 010, 057, ...), use an uppercase "T" in the tokens [T+] and [T-]. You can also use the length of [T+] miscellaneous GridOption to specify that the [T+] and [T-] tokens should only be padded up to 2 characters instead of 3.
•You can use the [t+] token in an ordinal token. So for example, a text sequence such as [t+][.t+] day of the year would convert to 51st day of the year.
