Header Card Description: Miksi viikossa on 7 päivää ja ja vuorokaudessa 24 tuntia? Mistä periytyy se, että tunti jaetaan 60 minuuttiin ja edelleen 60 sekuntiin? Miksi Ranskassa oli välillä 10 päiväinen viikko? Kuka siirsi ajanlaskun alkamaan Jeesuksen oletetusta syntymävuodesta? Miksi vappupäivä 1921 oli 20 minuuttia lyhyempi kuin muut päivät? Ajanlaskuun liittyviistä kiemuroista ja tarinoista kertoo Seppo Heikkisen toimittamassa ohjelmassa Helsingin yliopiston almanakkatoimiston erikoissuunnittelija Asko Palviainen. 8 controls, 10 labels Card JSON { "controls": [ { "destination": { "type": "series", "uri": "yleareena://items/1-50449678" }, "icon": { "id": "chevron-left", "version": "1750676272" }, "style": { "iconPosition": "left", "variant": "tertiary" }, "tag": "series", "title": "Ajan kummallinen historia", "type": "navigator" }, { "audience": { "authenticated": false }, "destination": { "authentication": [ "yle-api" ], "uri": "https://areena.api.yle.fi/v1/ui/controls/play/1-50409966?language=fi&v=10&client=yle-areena-web" }, "tag": "play", "type": "reference" }, { "audience": { "authenticated": true }, "destination": { "authentication": [ "yle-api" ], "uri": "https://areena.api.yle.fi/v1/ui/controls/play/1-50409966?language=fi&v=10&client=yle-areena-web" }, "tag": "play", "type": "reference" }, { "analytics": {}, "destination": { "type": "program", "uri": "yleareena://items/1-50409966" }, "functionality": { "id": "queue" }, "tag": "queue", "type": "activator" }, { "analytics": {}, "destination": { "type": "program", "uri": "yleareena://items/1-50409966" }, "functionality": { "id": "share" }, "icon": { "id": "share", "version": "1750676272" }, "style": { "iconPosition": "left", "variant": "tertiary" }, "title": "Jaa ohjelma", "type": "activator" }, { "analytics": {}, "audience": { "authenticated": false }, "backgroundColor": "#00000000", "functionality": { "id": "login" }, "icon": { "id": "icon-favorite-off", "version": "1750676272" }, "style": { "iconPosition": "left", "variant": "tertiary" }, "title": "Lisää omalle listalle", "type": "activator" }, { "audience": { "authenticated": true }, "destination": { "authentication": [ "yle-api" ], "uri": "https://areena.api.yle.fi/v1/ui/controls/favorites/1-50449678?language=fi&v=10&client=yle-areena-web" }, "type": "reference" }, { "destination": { "uri": "https://yleawsaudioipv4.akamaized.net/mediaredirect/78-edd86f781435496f87b528ea8b6dc506.mp3" }, "icon": { "id": "icon-download", "version": "1750676272" }, "tag": "downloadLink", "title": "Lataa tiedosto", "type": "navigator" } ], "description": "Miksi viikossa on 7 päivää ja ja vuorokaudessa 24 tuntia?
