Thank you for using Time & Date! This update makes it easier to save, find, and share your calculations. We’ve added dedicated views for each task—use Calculator to compute values, History to locate saved records, Calendar to review dated entries, and visual charts with file transfer options for easy sharing. Review your saved details effortlessly before sharing readable results. Thank you for relying on the app for all your time and date planning needs. Save and review calculations Calculator History stores named, read-only calculation records. Enter a name when saving, then use search to locate the record later without entering the calculation again. Review its saved details, share an individual record, or delete it when it is no longer useful. On iPad, the History list appears beside the selected record. Select another item to review its details while keeping the list available for browsing. History records containing dates can also appear in Calendar. Each qualifying record appears once on its saved day, including calculations containing several dates. Records without dates are excluded. Select a day to review its information, or hold the day to open details and access its saved records. Compare time entries visually Time-column calculators now offer charts for reviewing entries. Compare their values visually, read labels along the horizontal axis, and scroll horizontally through longer lists. The chart represents the entries you added. Use it with the entry list and total to review durations and individual contributions to a result. History transfers use a separate JSON file. CSV export provides a table for spreadsheet use. Importing an exact copy of an existing History record skips that duplicate, preventing repeated imports of the same saved data. Review records individually, retain the calculations you need, and delete items that are no longer useful. PDF sharing is available for calculator results, tracked dates, charts, and History. Create a readable document when you need a reference copy or want to send details to someone else. Choose CSV for a spreadsheet, PDF for a readable document, or History JSON when transferring saved History records. Each format serves a different purpose and has a separate export option. Manage tracked dates and records Adding a tracked date saves an initial record immediately. Complete its title and details later; closing the entry screen does not discard the initial record. Search tracked dates by title, tag, or date text. Use optional tags to group related events, appointments, deadlines, or personal dates. Use tracked dates for events and deadlines you want to monitor. Titles identify individual dates, tags group related items, and search narrows a longer list. Tracked dates remain separate from Calculator History: use dates for events and deadlines, and History for named calculation records you want to review or share later. On iPad, calculator and History views display a list beside the selected detail. Review an item while keeping the list available, then select another when needed. More groups History, Pro, Backup & Data Transfer, Settings, Help, and About in one location, with navigation for opening the information or tools in each section. Back up and transfer information Open Backup & Data Transfer in More to access project backups, tracked dates, and Calculator History transfer options. Select the data type and format required for the task. Project files, tracked-date files, and History files have separate import and export options. History also supports PDF documents and CSV tables for spreadsheets.
