You can use Roman numeral tokens to display the numbers corresponding to the day, week, month, quarter and year.

The big differences between Roman and Arabic numerals (the ones we use today) are that Romans didn't have a symbol for zero, and that numeral placement within a number can sometimes indicate subtraction rather than addition.

I |
The easiest way to note down a number is to make that many marks - little I's. Thus I means 1, II means 2, III means 3. However, four strokes seemed like too many.... |

V |
So the Romans moved on to the symbol for 5 - V. Placing I in front of the V — or placing any smaller number in front of any larger number — indicates subtraction. So IV means 4. After V comes a series of additions - VI means 6, VII means 7, VIII means 8. |

X |
X means 10. IX means to subtract I from X, leaving 9. Numbers in the teens, twenties and thirties follow the same form as the first set, only with X's indicating the number of tens. So XXXI is 31, and XXIV is 24. |

L |
L means 50. 40 is XL 10 subtracted from 50. And thus 60, 70, and 80 are LX, LXX and LXXX. |

C |
C stands for centum, the Latin word for 100. A centurion led 100 men. We still use this in words like "century" and "cent." The subtraction rule means 90 is written as XC. Like the X's and L's, the C's are tacked on to the beginning of numbers to indicate how many hundreds there are: CCCLXIX is 369. |

D |
D stands for 500. CD means 400. So CDXLVIII is 448. (See why we switched systems?) |

M |
M is 1,000. You see a lot of Ms because Roman numerals are used a lot to indicate dates. For instance, 1998 is written as MCMXCVIII. |

Larger numbers were indicated by putting a horizontal line over them, which meant to multiply the number by 1,000. Hence the V at left has a line over the top, which means 5,000. This usage is no longer current, because the largest numbers usually expressed in the Roman system are dates, as discussed above.
