The World Season Calendar is a proposal for calendar reform by author Isaac Asimov.[1] In this calendar, the year is divided into four seasons of 13 weeks each. The calendar for each season always has the following form:
| Sun | Mon | Tue | Wed | Thu | Fri | Sat |
|---|---|---|---|---|---|---|
| 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| 8 | 9 | 10 | 11 | 12 | 13 | 14 |
| 15 | 16 | 17 | 18 | 19 | 20 | 21 |
| 22 | 23 | 24 | 25 | 26 | 27 | 28 |
| 29 | 30 | 31 | 32 | 33 | 34 | 35 |
| 36 | 37 | 38 | 39 | 40 | 41 | 42 |
| 43 | 44 | 45 | 46 | 47 | 48 | 49 |
| 50 | 51 | 52 | 53 | 54 | 55 | 56 |
| 57 | 58 | 59 | 60 | 61 | 62 | 63 |
| 64 | 65 | 66 | 67 | 68 | 69 | 70 |
| 71 | 72 | 73 | 74 | 75 | 76 | 77 |
| 78 | 79 | 80 | 81 | 82 | 83 | 84 |
| 85 | 86 | 87 | 88 | 89 | 90 | 91 |
The seasons of the year are named A, B, C, and D; they correspond to the following seasons:
| Northern hemisphere | Southern hemisphere | |
|---|---|---|
| A | Winter | Summer |
| B | Spring | Autumn |
| C | Summer | Winter |
| D | Autumn | Spring |
December 21, which is on or near the time of the northern winter solstice on the Gregorian calendar, is called A-1 on the World Season Calendar.
Since each of the four seasons contains 91 days, there are 91 × 4 = 364 days in all four seasons. To make 365 days, an extra day called Year Day is added at the end of season D. Year Day is day D-92, and is not assigned a day of the week.
During leap year, an extra day called Leap Day is added at the end of season B. Leap Day, when it occurs, is day B-92, and is not assigned a day of the week.
Examples
| Gregorian | World Season |

| January 1 | A-12 |
| April 1 | B-11* |
| July 1 | C-11 |
| December 1 | D-73 |
| December 21 | A-1 |
*Add one day during leap year.
