The day has six windows. Your body knows which one it is in.

Ayurveda’s daily routine is not a schedule someone invented. It is an observation that the body’s capacities arrive in a predictable order after sunrise. Learn the order and most decisions about food, work and sleep answer themselves.

Dinacharya — the day's clock

Tap a band to read that window

Why sunrise, not the clock

6am in December is not 6am in June.

Most summaries of dinacharya give you fixed hours: Kapha 6 to 10, Pitta 10 to 2, Vata 2 to 6. That is a simplification of the actual rule, which measures from sunrise.

Summers in India, sunrise moves by about ninety minutes between June and December. Follow the fixed version in winter and you are doing your Kapha morning in the dark, an hour before the window has opened.

The six windows

Measured from sunrise, not from the clock

Kapha

Sunrise to +4h

Heavy, slow, steady

Wake near sunrise, scrape your tongue, drink warm water, then move: a walk, stretching, anything. Eat a light warm breakfast. This is the window where sitting still makes the whole day feel sluggish.

Pitta

+4h to +8h

Hot, sharp, focused

Digestive fire is at its peak, so this is when your largest meal belongs. It is also your sharpest thinking: do the hard task before lunch, then eat properly rather than at your desk.

Vata

+8h to +12h

Light, mobile, scattered

Attention frays. Good for creative work in short blocks, conversation, and admin. Sip something warm; the 4pm crash is usually dehydration and a skipped lunch, not a caffeine deficiency.

Kapha

+12h to +16h

Settling, cooling

The body starts closing down. Eat light and early: soup, khichdi, something cooked. Dim the lights an hour before bed so melatonin is not fighting your ceiling lamp.

Pitta

+16h to +20h

Repair, processing

Deep sleep and tissue repair. The same fire that digested lunch turns into restlessness if you are awake and scrolling. A late-night second wind feels like energy and costs you the morning.

Vata

+20h to sunrise

Light, dreaming

The lightest, most dream-heavy sleep. Waking towards the end of this window feels markedly easier than dragging yourself out of the Kapha hour that follows.

If you change one thing

Move the big meal to midday.

Of everything on this page, this is the change with the most behind it. Eating your largest meal at noon rather than at 9pm lines up with the body’s own digestive rhythm, and it is the intervention people report the fastest difference from: better sleep, lighter mornings, less of the 11pm hunger that is not hunger.

It is also the hardest one to arrange around a job. Start with two days a week. A proper lunch and a small dinner, twice, is worth more than a perfect week you abandon.
