Mechanical pencil on paper. Sketch by me, 2015.

This runs from September 23, 2015 (8:20 UTC) to March 20, 2016 (4:30 UTC).

It features the lunar phases.

The “revised months” are (for now) named after the Chinese Zodiac.

(I don’t really have names for the thirds of the zodiac or revised months.)

The solar terms are numbered as beginning at 315°.

The pentads are numbered as beginning with the March equinox.

I have calculated the beginning times of the pentads for the next six months (all times in UTC):

Many spaces are blank and unnamed because there is still naming I have to decide on!

(The numbered squares are pentads.)

17/72 (80° to 85°)

Say you divide a tropical year (beginning and ending with the vernal equinox) into 72 parts based on 5° divisions of 360°.

(These 5° divisions have been named for some time throughout Asia, and are known as 候... pronounced hou in Mandarin, hau in Cantonese, kou in Japanese. This term is also translated as "pentad" in English.)

If you begin a cycle of these 5° divisions with the vernal equinox, it means 17/72 (80° to 85°) will begin June 11, 2015, at 05:25 UTC and end June 16, 2015, at 10:58 UTC.

(In the PDT timezone, which is used this time of year along the North American Pacific coast, this division begins June 10, 10:25pm and ends June 16, 03:58am.)

You can convert June 11, 2015, 05:25 UTC to your local timezone to find out when 17/72 begins where you are.

16/72 (75° to 80°)

Say you divide a tropical year (beginning and ending with the vernal equinox) into 72 parts based on 5° divisions of 360°.

(These 5° divisions have been named for some time throughout Asia, and are known as 候... pronounced hou in Mandarin, hau in Cantonese, kou in Japanese. This term is also translated as "pentad" in English.)

If you begin a cycle of these 5° divisions with the vernal equinox, it means unit 16/72 (75° to 80°) will begin June 5, 2015, at 23:58 UTC and end June 11, 2015, at 05:25 UTC.

(In the PDT timezone, which is used this time of year along the North American Pacific coast, this division begins June 5, 4:58pm and ends June 10, 10:25pm.)

You can convert June 5, 2015, 23:58 UTC to your local timezone to find out when 16/72 begins where you are.

15/72 (70° to 75°)

Say you divide a tropical year (beginning and ending with the vernal equinox) into 72 parts based on 5° divisions of 360°.

(These 5° divisions have been named for some time throughout Asia, and are known as 候... pronounced hou in Mandarin, hau in Cantonese, kou in Japanese. This term is also translated as "pentad" in English.)

If you begin a cycle of these 5° divisions with the vernal equinox, it means unit 15/72 (70° to 75°) will begin May 31, 2015, at 18:39 UTC and end June 5, 2015, at 23:58 UTC.

(In the PDT timezone, which is used this time of year along the North American Pacific coast, this division begins May 31, 11:39am and ends June 5, 4:58pm.)

You can convert May 31, 2015, 18:39 UTC to your local timezone to find out when 15/72 begins where you are.

14/72 (65° to 70°)

Say you divide a tropical year (beginning and ending with the vernal equinox) into 72 parts based on 5° divisions of 360°.

(These 5° divisions have been named for some time throughout Asia, and are known as 候... pronounced hou in Mandarin, hau in Cantonese, kou in Japanese. This term is also translated as "pentad" in English.)

If you begin a cycle of these 5° divisions with the vernal equinox, it means unit 14/72 (65° to 70°) will begin May 26, 2015, at 13:33 UTC and end May 31, 2015, at 18:39 UTC.

(In the PDT timezone, which is used this time of year along the North American Pacific coast, this division begins May 26, 06:33am and ends May 31, 11:39am.)
