How the year is divided
Your Cardology year runs from one birthday to the next. It’s split into seven periods of 52 days each, which adds up to 364 days. The extra day, or two in a year with 29 February, goes at the end of the last period.
The periods always start on your birthday and run in the same order: Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune.
An example: a 10 March birthday
For someone born on 10 March, in a year without 29 February, the periods fall like this:
| Period | Dates |
|---|---|
| Mercury | 10 Mar to 30 Apr |
| Venus | 1 May to 21 Jun |
| Mars | 22 Jun to 12 Aug |
| Jupiter | 13 Aug to 3 Oct |
| Saturn | 4 Oct to 24 Nov |
| Uranus | 25 Nov to 15 Jan |
| Neptune | 16 Jan to 9 Mar |
Every birthday has its own dates. Find yours on the birth card by birthday page.
What each period means
- Mercury
- Communication, learning and short trips. Things tend to move quickly.
- Venus

- Mars

- Jupiter
- Growth, money, work opportunities and generosity. Seen as the most positive period.
- Saturn
- Responsibility, hard work, health and limits. Seen as the most challenging period.
- Uranus
- Change, surprises, independence and gut feelings.
- Neptune
- Dreams, imagination, travel, rest and wrapping up the year before your birthday.
How to use the periods
Treat each period as a theme to reflect on, not a prediction. At the start of a period, read its theme and ask what it might mean for you. It can help to keep a short journal, and look back at the end of the period to see whether the theme fitted.
This website shows the dates and themes of your periods. The full Cardology system also gives a specific card for each period from your yearly spread, which isn’t covered here.
