telling the time Telling the time in Welsh is pretty simple really - as you'd say 'quarter past three' in English, so you would in Welsh, although you couldn't say 'three fortyfive - that would be 'quarter to four' instead. The only other thing you need to remember is that some vigesimal numbers are used instead of the equivalent decimal number: 12 - 'deuddeg' instead of 'undeg dau' 15 - 'pymtheg' instead of 'undeg pump' 20 - 'ugain' instead of 'dauddeg', (note that it gains an 'h' after 'ar', becoming 'hugain') 3.00 tri o'r gloch 3.05 pum munud wedi tri 3.10 deng munud wedi tri 3.15 chwarter wedi tri 3.20 ugain munud wedi tri 3.25 pum munud ar hugain wedi tri 3.30 hanner awr wedi tri 3.35 pum munud ar hugain ibedwar 3.40 ugain munud i bedwar 3.45 chwarter i bedwar 3.50 deng munud i bedwar 3.55 pum munun i bedwar 4.00 pedwar o'r gloch second eiliad minute munud hour awr o'clock o'r gloch quarter chwarter half hanner to i past wedi yn gwmws precisely am at tua at about erbyn by cyn before ar ôl after o ... tan ... from ... till ... o ... ymlaen from .... onwards rhwng ... a ... between ... and ...
