Here are the basic words for parts of dates and times. These words are not for durations, they are for specifying absolute times like "three in the afternoon" or "Tuesday".
Table 5.3. Date and Time Words
| agas- | clock-year- | calendar year |
| tifo- | clock-month- | calendar month |
| hetpi- | clock-month-day- | day of the month |
| feu- | clock-week-day- | day of the week |
| filaf- | clock-hour- | hour of the day |
| ipilo- | clock-minute- | minute of the hour |
| lolai- | clock-second- | second of the minute |
| (not pronounced) | ; | (date divider) |
| (not pronounced) | : | (time divider) |
To form a month or a day of the week, put a number before the time word, creating a compound root. The months are numbered one through twelve for January through December. The days are one through seven for Monday through Sunday (European style). The same plan can be followed for years, hours, and so on, of course.
Example 5.3. Tuesday
Pa 2feuhu 17tifohu. Belief 2+clock-week-day+time 17+clock-month+time. It's on Tuesday the 17th.
As in English, dates and times can also be expressed compactly as strings. Dates are written with ";" as a divider: 2009;02;14. Times are written in 24-hour format with ":" as the divider: 10:11:12.
Dates and times are always in "big-endian" style, with the larger units first. So it's year;month;day and hours:minutes:seconds.
