Principles

1. It is desirable to abbreviate time designations whenever the complete designations v^ould be too crowded or require o size of lettering too small to be legible.

2. Only stondord or recognized obbreviations should be used. Procedures

1. IN GENERAL, time-scale designations should not be abbreviated until the possibilities of other methods have been considered Isuch as staggering or placing verticollyl.

2. DAYS. The days of the week should conform to the usual method of abbreviation except that Tuesday and Thursday should generally be written '"Tue" and "Thu" in order that all may be of equal length and

emphasis.

3. MONTHS. Months also should generally conform to three-letter abbreviations in order that all months may be of equal length.

Note: If it is importoni to retain horizontal reodino but sufTicient space lor stondord obbreviolion is not ovoiloble, the initio! letters of the month con sometimes be used: JfMAMJJASOND. This form is not recommended for generol use.

Another oliernolive sometimes used to retain horizontal reading is to indicate months by numerals: I 2 3 4 5 6 7 8 9 10 11 12. This is not oeneroMy recommended becouse many people do not readily associate month numbers with month names.
