History Toolkit
How to use
What it does
Tools for history and chronology: build vertical or horizontal timelines to order events, look up Chinese dynasties and their approximate date ranges by year, convert between the common era and the sexagenary cycle, and compute age and zodiac from a birth date. Useful for organising reading notes, exam preparation, or recording family oral history.
How to use it
Switch modules at the top. The timeline accepts events and dates added row by row with drag reordering, and exports as an image or text once finished; the dynasty lookup takes a year and returns which dynasty held power and in what period; the cycle converter works in both directions between a CE year and a sexagenary name; the age tool takes a birth date and reports exact years, months and the zodiac sign.
FAQ
What can a finished timeline be saved as?
An image or a text export. Add the events one by one, drag them into order, and the file drops straight into notes or slides.
Which directions does the Ganzhi conversion support?
Both ways — a CE year to its sexagenary name and back again, so you can decode a stem-branch year in an old text or restore a CE year from one.
How precise is the age calculation?
Enter a birth date and it reports exact years and months plus the zodiac sign — plenty for chronologies or checking anniversaries.
